Three things we learned on Day 28

FLORHAM PARK, N.J. -- Observations from Wednesday:

1. Looks like no Wildcat in the preseason: The starters will play into the third quarter Sunday night against the Panthers, but Rex Ryan said he doesn't envision Tim Tebow and Mark Sanchez on the field together. In other words, he's not planning to unveil the Wildcat. Because Sanchez won't play in the final preseason game, it means the world won't get to see the over-hyped Wildcat until Week 1 against the Bills. They'd better hope it's not a flop.

2. Tough roster decisions: One of the toughest decisions will be at wide receiver. Chaz Schilens, once thought to be a lock, could be on the bubble because he hasn't been on the field. Schilens (ankle) will miss his second game this week. Ryan said he feels "pretty good" about Schilens, but he didn't rule out the possibility of adding a veteran. They'll probably keep five or six receivers, and we know Santonio Holmes, Stephen Hill, Jeremy Kerley and Patrick Turner are locks. Schilens is a four-year veteran, which helps his cause. It also helps that he has a $500,000 guarantee. Bottom line: The former Raider still is largely an unknown and time is running out.

3. Early thoughts for 2013: Ryan said he's open to the idea of practicing against another team next summer. The Patriots are doing it as we speak, practicing down in Tampa against the Bucs. Earlier, they hosted the Saints in Foxborough. The Jets thought about joining the trend, but they opted against it this year because they're installing a new offense and wanted concentrate on that. A long, long time ago, the Jets faced the Redskins and Giants in joint practices. During the Herm Edwards era, they traveled to Albany to practice with the Giants, but that turned chippy -- and that was the end of that.
