W2W4: Green & White scrimmage

CORTLAND, N.Y. -- The highlight of training camp occurs at 6 p.m. Saturday at the SUNY Cortland football stadium -- the Jets' annual Green & White scrimmage, open to the public. What to watch for:

1. Best on best: With so many jobs undecided, the Jets will play first-team offense versus first-team defense for portions of the controlled scrimmage, according to Rex Ryan. Usually, they try to avoid that to keep the intensity level under control, preventing injuries, but Ryan is in a heavy evaluation mode and wants extreme competition on both sides of the ball.

2. QB competition: Technically, it's Geno Smith's turn to be the first man up, according to the rotation, but the team hasn't said which quarterback will take the first reps. Either way, both will get a chance to work with the starters, according to Ryan. The scrimmage is virtually meaningless for Mark Sanchez; the Jets know what he can and can't do. The spotlight will be on the rookie to see if he can maintain his impressive camp.

3. Rookie debut: John Idzik's first draft class will be on display. Aside from Smith, the most compelling player is CB Dee Milliner (No. 9 overall pick), who got a late start because of his contract dispute. He's really had only one full practice, but the former Alabama standout is expected to see some time. DT Sheldon Richardson and LG Brian Winters also could be in the starting lineup.

4. 'Cat out of the bag?: Ryan has said he plans to use the Wildcat and read-option this season, but will they show them in such a public setting? You know how football coaches are; they're paranoid about this kind of stuff.

5. Young receivers: Stephen Hill and Clyde Gates have impressed in camp, a positive development for a team that was almost freaking out over the receiver situation in minicamp. Hill has caught just about everything on the practice field, but he tends to lose concentration in big spots. This hardly qualifies as "big," but it's as big as it gets in Cortland.
