Jet fans should be patient. Even if you're pleased as pie about everything Idzik has done so far, the moves he's made are still largely very conservative. He shored up the defense and the running game, but it's still a passing league, and the Jets are still deficient in that department. People are optimistic about Geno, but he went #39 overall (with a few QB needy teams passing on him twice) for a reason. The Jets receivers and TEs are a below average group (being generous here) until someone proves otherwise. The Jets still don't have a clear plan about the future of the coaching staff, and we could see a disconnect between Rex's short term goals, and Idzik's long term goals this year.
Next year is when the full rebuild takes place. Rex proves himself, or he's gone. Sanchez probably doesn't have that much of a chance. The team will have as many as five extra draft picks and as much as $50M in cap space. That's when the team will get built. This year was a little foundation work in preparation for the coming overhaul, that's all.
After the Tannenbaum Era, this team could use a little conservative. I like that Idzik seems impervious to outside pressure, and just does his job. Though certainly not the first round picks I wanted, I think in three years we'll be pretty pleased with having the players he drafted on this roster.
