The numbers say that this will be the worst season of Erik Spoelstra's head-coaching career.

But the eye test paints this agonizing journey for Spo and the Miami Heat in an entirely different light. His ability to handle a relentless, unending stream of adversity has been every bit as impressive as the championship campaigns that he led in the past.

This is his seventh year occupying the premier sideline seat inside AmericanAirlines Arena, but it might feel more like his first. The expectations have changed, right along with his methods of meeting them and the players tasked with carrying out his vision.

Less than 10 months back, Spoelstra was coaching in his fourth consecutive NBA Finals. Just six players who logged time during that playoff push still suit up for the Heat, and only five are able to see the floor, with Chris Bosh forced out of action by blood clots on his lung.

If Spoelstra needed name tags to help make his in-game huddles more efficient, who could blame him? He's had 18 guys make at least 15 appearances and average double-digit minutes. He just rolled out his 30th starting lineup of the season, which matched a franchise record set by the 15-win 2007-08 squad. (This team has 34 wins and counting.)

The Heat missed the playoffs by 22 games that year. This group currently sits at seventh in the Eastern Conference standings.

If Spoelstra's prolific past didn't completely silence his critics, his present should finish the job.

"It should be common knowledge by now he's an excellent coach," San Antonio Spurs coach Gregg Popovich said, per Shandel Richardson of the Sun Sentinel. "He knows what wins and what loses. He's comfortable in his own skin. He teaches well. He's going to make fair demands on whoever is available."

Even if "whoever is available" changes on a nightly basis.

Miami's injury report isn't very social-media friendly, as there's often more information to convey than Twitter's 140-character limit allows.

Bosh, rookie Shabazz Napier (sports hernia) and Josh McRoberts (knee) are all out for the year.

Surprise star Hassan Whiteside is playing with 10 stitches in his right hand.

Luol Deng (knee) and Udonis Haslem (illness) missed Miami's last game.

Dwyane Wade recently had fluid drained from his left knee.

Just think, for a moment, about Miami's plan to survive last summer's loss of LeBron James. What did it involve? Bosh stepping back into a primary role, McRoberts and Deng splitting glue-guy duties, Napier outperforming his draft position (24th overall) and, hopefully, Danny Granger playing remotely close to the levels that he had previously reached.

Of all those possibilities, only Deng's chance at serving as a jack-of-all-trades remains in play—if his body cooperates. The 29-year-old said that the heavy workloads he's carried and injury problems he's battled in the past have aged him considerably.

"I feel 45," he told Basketball Insiders' Jessica Camerato. "I feel old."

Losing James alone is enough to wreck a franchise. But to have the emergency recovery plan also crumble borders on cruel and unusual punishment.

Unless you ask Spoelstra, who refuses to use any of the excuses that are readily available to him.

"We've had to deal with a lot of adversity, but I like the group because we haven't made excuses; we haven't felt sorry for ourselves," Spoelstra said, per Tim Bontemps of the New York Post. "We've just worked to try to find solutions, and we're in a playoff race."

That's pretty incredible, even if postseason spots are handed out like participation trophies in the pillow-soft Eastern Conference. It's not only that the Heat are in a playoff race, but it's also that their engine is still running despite being torn apart and rebuilt with pieces from basketball's scrapyard.

Whiteside was honing his craft on YMCA courts before the Heat gave him a shot in November. With the help of Spoelstra and Heat assistant coach Juwan Howard, Whiteside has emerged as a double-double machine and one of the league's best shot-blockers.

Miami grabbed shooting guard Tyler Johnson and brought back versatile forward Henry (formerly Bill) Walker from the D-League. Michael Beasley's season started in China before he returned for his third stop in South Beach.

Each of those three has battled expected inconsistency, but Spoelstra has still squeezed some meaningful production out of them.

"I don't know where we'd be without guys from the D-League or China," Spoelstra said, per Joseph Goodman of the Miami Herald.

We can take an educated guess where they'd be: lottery-bound for the first time since that dreadful 2007-08 campaign.

The Heat have needed everything that their unexpected contributors have provided.

Not all of the numbers are pretty, but they don't have to be. This has been a season defined by survival—not style points.

And Spoelstra has equipped his team with those survival instincts. He has his players believing in themselves when logic says that they don't have enough bodies to compete at a high level, via Bleacher Report's Ethan Skolnick:

Spoelstra has seamlessly integrated Goran Dragic into the offense, creating rhythm between Wade and a backcourt mate unlike any he's ever had. And even though Dragic is new to the program and facing the uncertainty of free agency this summer, Spoelstra has the point guard playing every bit as hard as the rest of this injury-riddled roster, via Jason Lieser of The Palm Beach Post:

Spoelstra has empowered his players with freedom and trust. He knows when his guys need a lift from him and when they should pick each other up.

"There are times during certain games when Heat coach Erik Spoelstra just walks away from the team huddle and lets Udonis Haslem have the floor," Goodman noted.

Spoelstra has the individuals on this roster invested in their collective success. It's hard to overstate the importance of that when guys like Dragic and Deng are simultaneously auditioning for their next contracts (both have player options for 2015-16).

Countless forces have tried tearing this team apart.

James' exit was tough to stomach; the fact that he closed Miami's championship window on his way out was even harder to take. Any optimism that survived the departure has been under constant attack by the injury bug. Continuity, typically a key ingredient for good chemistry, has never been an option.

But somehow, Spoelstra has made this work.

"The reality is that throughout the season they have not had lineups with the abilities to sustain," wrote the Sun Sentinel's Ira Winderman. "To Erik Spoelstra's credit, he has been able to find combinations that have worked."

"Combinations" that no one could have fathomed at the start of the season, or even at the halfway point. But all the body blows thrown the coach's way haven't put Miami on the canvas yet.

The Heat are still standing and tossing a few counterpunches of their own. That fighting spirit, that refusal to accept fate, that willingness to push past every obstacle—it all starts with Spoelstra.

This might be the least successful year on his resume, but it stands as one of his finest works to date.
