MLB's free agency has unfolded in bizarre fashion, with some of the top players getting signed late in the offseason or not at all.

At the heart of the situation are some of the most divisive topics in MLB — tanking and analytics — with the league, team, and players pointing fingers.

While accusations of collusion swirl, no one is quite sure what to make of the situation.

About 30 disgruntled free agents trekked to Bradenton, Florida, this week for an unusual spring training camp.

The camp is not being hosted by a team, but by the MLB players union, hoping to keep jobless MLB players active and in-shape while they wait and hope for a contract offer or camp invite from a team.

It's the latest chapter in MLB's free agency saga, which has seen some of the top players get signed late in the offseason or not at all.

As of Friday, according to ESPN's MLB free agent tracker, about 60 players still remain on the market, nearly one-third of the free agent class, including big names like Jake Arrieta and Mike Moustakas.

"I have no idea what the hell is happening," said MLB agent Joshua Kusnick. Kusnick said he entered the offseason with six free agents and has gotten three of them deals so far.

"It's disheartening. That's a good word," Kusnick said.

At the heart of the issue are some of the most divisive topics in MLB — tanking, analytics, and collusion, the latter of which has been a problem for baseball before. The debate has seen both parties finger-point over an unusually cold "hot stove" season.

Slowly, some of the top free agents have found homes, but vitriol was strongest in February, when notable agent Brodie Van Wagenen alleged collusion by MLB teams, threatening a work strike if teams did not spend more to sign free agents. Later, the MLBPA executive director Tony Clark released a statement saying that the lack of signings, despite "records highs" in revenue, threatened the integrity of the game.

MLB responded in its own statement, saying it's not unusual for a number of free agents to remain unsigned in February, adding "what is uncommon is to have some of the best free agents sitting unsigned even though they have substantial offers, some in nine figures."

The comment drew the ire of agents like Kusnick, who questioned why MLB was commenting on reported deals — the MLB's collective bargaining agreement (CBA) forbids the commissioner's office and the union from commenting on the value of players or possible deals.

Are analytics to blame?

MLB's statement also noted the role of analytics in the stagnant free agent market. Teams have fallen back on analytics as one of the biggest reasons why so many free agents haven't been signed. Teams now have internal projections for how much a player can be expected to produce on the field and how much that is truly worth. Gone are the days of teams paying high prices for production that never really comes.

Juan Francisco is one of about 30 unsigned players at a training camp for free agents. Chris O'Meara/AP One team executive pointed to widespread front office turnover in recent years and the shift toward younger, more analytically driven front offices. This offseason, that shift has coalesced into a league-wide movement.

"The dynamics of signing contracts changed so dramatically in recent years," said Murray Cook, a scout for the Detroit Tigers and former GM of the New York Yankees and Cincinnati Reds.

"You have the occasional 10-year contract, which has really proven to be so onerous to management and ownership because players who sign those contracts, the last five years, they’re not non-productive, necessarily, but production decreases dramatically. And with the analytics today, the analytics are saying, after the age of whatever it is, performances starts going downhill."

Some, like Kusnick, remain skeptical.

"So I have to accept in this offseason that analytics just took over everybody at the same time?" Kusnick said. "All 30 front offices decided, 'We've got analytics. We're all going to interpret these data sets the exact same way for the same players that we're all looking at together.'

He continued: "I gotta buy that, and then at the same time, the accusations that I've heard that agents misread the market. Okay, the teams all got smarter, and at the exact same time, the inverse is true, that every agent misread the market and players are greedy. I gotta believe that? F--- no. I don't believe that."

The tanking epidemic.

On Tuesday, February 27, The Tampa Bay Times reported that the players union filed a grievance against four teams, the Miami Marlins, Tampa Bay Rays, Oakland A's, and Pittsburgh Pirates, for not spending revenue-sharing money to improve the on-field product, a rule in the CBA.

This offseason, the Marlins, Rays, and Pirates all traded star players in Giancarlo Stanton, Evan Longoria, and Andrew McCutchen, respectively. The Marlins, in particular, have come under fire for stripping down payroll in an effort to rebuild.

According to The New York Times, Clark said this offseason that it's not just one or two teams rebuilding and avoiding spending, but 10 teams, or one-third of the league, are not actively trying to win.

Teams view the idea of tanking differently. Cook said that tanking does not exist — teams never intentionally lose, but everyone eventually has to rebuild.

"It's called rebuilding," Cook said. "That's what we're doing this year, we're rebuilding. That's something clubs have to do. As I said, [the] Houston [Astros] just did it. Everybody's saying Houston did such a good job — the model by which we oughta operate. So, everybody is thinking that way."

The Astros famously stripped their roster, focusing instead on building up their farm system and developing young players, going 162-324 over three years. After three years of losing, they built back up and won the World Series in 2017.

MLB Commissioner Rob Manfred also disagreed with the term "tanking," telling reporters that each team wants to win but rebuilding is sometimes a necessary step.

Analytics play a part in tanking or rebuilding, too. One team executive said that internal projections show that signing star players to big contracts can be overrated — that the extra 2-3 wins a player can add is not worth it from a revenue standpoint.

The shift in thinking has turned draft picks into a higher commodity. Teams would rather develop draft picks, which are cost-controlled and under team control for longer. Signing a top free agent like Arrieta, for instance, would require giving up a compensatory draft pick to his former team.

Is it collusion?

Not everyone has agreed with Wagenen's suggestion that there could be collusion on the part of MLB teams.

Even Kusnick, who was animated about the subject, said he doubts collusion is actually occurring.

"I gotta entertain absolutely everything," he said. "Do I think it is? Realistically, it probably isn't."

Some players have been hesitant to call it collusion, despite their objections to the way the offseason has gone. Washington Nationals pitcher Sean Doolittle told The Washington Post: "I don't know enough about the moving parts behind the scenes to come right out and call it collusion, because that's a really serious charge. But the later you get in this process — and we're now in spring training — it does make you wonder what's going on. Because you hope that's not the case."

The team executive said nothing has changed internally about team-to-team competition.

"Teams still wanna beat the s--- out of each other," the executive said. "They're not communicating with each other about how not to get the players that would help their win productivity — it's just the opposite. Teams are getting smarter and smarter."

Still, Kusnick is baffled at how the market unfolded.

"The conversations this offseason, for me, there's a lot of uniformity in them, which is weird for 30 competing business entities to be processing the data and the money the same exact way at the same time in the same offseason with the same set of players."

He added: "You wanna use analytics? How did all 30 teams come to this conclusion by themselves? What would be the odds of that happening organically?"

The bigger hurdle on the horizon is labor negotiations — the CBA expires in 2021. The league and its players have enjoyed a peaceful relationship for years, but the dramatic shift seen this offseason could threaten the relationship.

Manfred tried to brush off those fears in February.

"I am a long-term thinker when it comes to labor relations," he said. "We have had an extraordinarily positive working relationship with the MLBPA over most of two decades. The fact that we've had some positive relationship over that period doesn't mean that there are not topics of which we have had disagreement — some of them more serious than others.

"I think one of the most important parts of good labor relations is the ability to get past those disagreements and move on."

In Bradenton and across the country, that hostility is growing the longer notable players sit at home waiting for an offer.
