@JetFan79 does not grasp how truly horrible this squad is. These "young" players you cite are not good...they are just the best the Jets have. Let's just look at the MMQB Top 400 list that just came out. Despite its obvious flaws coming from SI, it's at least a general barometer of the top 400 players in the league. The average team has 12.5 players; the Patriots lead the league with 20 players.
The Jets have far and away the fewest players in the list with only 5. The next worst teams, the Bears and Jaguars, each have 8. Its almost mathematically impossible to field a professional team and have that few players in the top 400. It gets worse.
74. Leonard Williams
93. Muhammad Wilkerson
105. Sheldon Richardson
350. Morris Claiborne
395. Quincy Enunwa
In this list, Wilkerson has eaten his way to become a laughingstock and is in fact a huge liability when his contract is factored in. Richardson has been the subject of trade rumors, as the Jets want to get rid of him due to attitude and off-the-field issues. Claiborne is essentially a huge draft bust who barely cracked the list. Enunwa is the 38th ranked WR in the league...a guy you singled out as a glowing example of the Jets youth.
The other players who you think could be good, linebackers and safeties, these are draft picks. Every team thinks/hopes they've struck gold. Given the Jets track record in the draft, it's highly unlikely they'll pan out as optimistically as you think.
The Jets aren't just the worst team in the NFL. They easily have the worst nucleus of young talent as well. And it isn't because they lack superstars...looking at the huge gap between 105 and 350 on the list, it confirms that they lack those solid foundational players as well.
This would be a terrible situation to bring a young, talented quarterback into. They are years and years away from being respectable. Outside of some very obvious lottery players who dropped into their laps, they have been the absolute worst drafting team in the NFL since Mangini left. It's very problematic that multiple GMs have come in and been as impossibly bad as the previous one. I suspect it's the organization, to bottom, and it's impossible to weed out the underlying issues save for an ownership change.
