The Jets came out firing in free agency this week. Now, the second wave of free agency has begun.

General manager Mike Maccagnan added a difference-maker on both sides of the ball with running back Le’Veon Bell and inside linebacker C.J. Mosley. He also bolstered his offensive line with the trade for Kelechi Osemele and gave new coach Adam Gase a slot receiver with the signing of Jamison Crowder. Maccagnan also re-signed defensive lineman Henry Anderson, who had a breakout season with the Jets last year.

So, now what?

Well, Maccagnan still has plenty of work to do and while the first days of free agency provide the sizzle, the next few weeks are where good GMs do their best work. The prices drop and value can be found for those with a sharp eye to find it.

It is unclear exactly how much salary cap space the Jets have remaining because all of the contracts they agreed to this week have not been filed yet. It is estimated that they have somewhere between $40-50 million left, though.

The Jets can’t spend all of that money. They need to set a chunk aside to sign their draft picks and the No. 3 pick overall will carry a decent cap number (probably around $5 million). They also will need some money for the season to sign players. So figure they really have $20-30 million still to spend.

That may sound like a lot, but it will go quickly. The Jets still have to sign a lot of players. They entered free agency with the fewest number of players under contract, just under 50. Rosters can go as high as 90 in the offseason. With that in mind, expect Maccagnan to be bargain hunting from here on out.

He shopped in the bargain aisle with the signing of Brian Poole to be their slot cornerback for one-year, $3.5 million. They also signed kicker Chandler Catanzaro. The terms were not available but it surely was a lot less than what Jason Myers got from the Seahawks (4 years, $15.45 million with $7 million guaranteed).

As for their remaining needs, there are a few that leap out.

They still do not have an edge rusher. It appeared they had landed their top target when Anthony Barr agreed to a deal, but he backed out a day later and returned to the Vikings. Most of the top pass rushers are off the board. Justin Houston remains a free agent, and it is possible he could be a bargain if there is not a healthy market for him.

The Jets do not have to fill all their needs in free agency. They are likely to draft a pass rusher with the third overall pick next month, but they probably still want to bring in a veteran there.

The Jets also may need to add another cornerback. Morris Claiborne is a free agent and the Jets look like they won’t bring him back. That would leave a hole on the outside, although the Jets gave Darryl Roberts a $6 million-per-year contract, so maybe they view him as a starter.

With Josh McCown still undecided about his future, backup quarterback is a need. Blake Bortles, Brock Osweiler, who played for Gase in Miami, and Trevor Siemian are some of the quarterbacks on the market.

Osemele is the only move the Jets have made on the offensive line. Center was considered an area of need for the Jets, but they might go with Jonotthan Harrison, whom they re-signed, there.

Beyond that, the Jets still need a run-blocking tight end and Maccagnan needs to add depth across the roster.

The fun stuff is over, but Maccagnan’s major work lies ahead.
