What we learned on Day 18

CORTLAND, N.Y. -- Observations from the press box:

1. Ankle, schmankle: Geno Smith probably could've used a day to rest his ankle, but he was out there, taking the majority of the first-team reps and limping through a series of rollout plays.

What are we to make of this? Well, you have to admire his determination; some players would've asked out. The larger issue, though, is the Jets' willingness to put him out there. It was only a mild sprain, a source said, but it still showed how much they want to keep him in the thick of the quarterback competition. The Jets are tired of Mark Sanchez's turnovers, and they want to give the rookie every chance to win the job.

That said, they won't force it. If Smith doesn't practice well this week, it wouldn't surprise me if Sanchez gets the start Saturday night against the Jaguars.

2. Marty gets mad: We saw the ornery side of Marty Mornhinweg. The offensive coordinator chided Smith for taking a sack, he lit into Braylon Edwards (twice) for not hustling at the end of plays and he ordered the offense to re-huddle a couple of times. Smith noted that Mornhinweg was on his case in practice, basically telling him, "No limping allowed."

I noticed an increase in intensity from a few coaches. Maybe this was Rex Ryan's way of creating a sense of urgency after the penalty-filled loss in Detroit.

3. Mercurial McKnight: I'd like to provide some commentary on how I think the enigmatic Joe McKnight no longer is guaranteed a roster spot ... except I'm not getting into that.
