A few takeaways from a busy Tuesday for the New York Jets, who re-signed quarterback Josh McCown and reached deals with quarterback Teddy Bridgewater, cornerback Trumaine Johnson, running back Isaiah Crowell and linebacker Avery Williamson:

1. Life after Kirk: Knowing it would be tough to lure Kirk Cousins to New Jersey, the Jets formulated a two-pronged Plan B: McCown and Bridgewater. Some people might snicker, calling them old (McCown) and gimpy (Bridgewater), but it's actually a sound, short-term plan. Now comes the tough part: They need a long-term solution, and that means drafting one of the Big Four. This is reminiscent of the 2016 Philadelphia Eagles, who traded for Sam Bradford (a brief rental, as it turned out), signed Chase Daniel and drafted Carson Wentz. If you throw enough against the wall, something has to stick, right?

2. Youth is served: The Jets went into this determined to limit their long-term commitments to players entering free agency for the first time. If you do that, you're buying a player's prime years. General manager Mike Maccagnan followed through on the plan. Check out the ages: Crowell and Bridgewater are 25. Williamson is 26. Johnson, coming off two franchise-tagged years, is 28. Bridgewater will be on a one-year contract, but Crowell, Williamson and Johnson should be around for the long haul.

3. Odd men out: The addition of Williamson, who played middle linebacker for the Tennessee Titans, probably means the Jets will move on from Demario Davis, a free agent. It's too bad because Davis is coming off his best year, and he's a good locker-room guy, but business is business. The two sides were far apart on a new deal, and the Jets decided to target Williamson. At quarterback, Bryce Petty looks to be a goner. Christian Hackenberg's roster spot also is in jeopardy, assuming they draft a quarterback. It wouldn't be a shock if they shop Hackenberg before the draft.

4. The big splash: The key to this entire free-agent frenzy is Johnson, who plays a premium position and will be pulling down one of the biggest salaries in team history (an estimated $15 million per year). Keep in mind the Jets gave Darrelle Revis $14 million per year when they brought him back in 2015. They whiffed on Revis, who was 30 and disinterested upon his return. Presumably, they will get the best of Johnson, who has lockdown ability.

5. What's next: They have a hole in the middle of their offensive line. They expressed interest in center Weston Richburg, but he agreed to a deal with the San Francisco 49ers. Ryan Jensen still is on the market. The Jets must come out of this with a starting center. They also have needs at tight end, defensive end and outside linebacker.
