Rex report: Ready, set, stretch

CORTLAND, N.Y. -- The tweaks are back.

The Jets, who dealt with a rash of hamstring injuries in minicamp, are experiencing another run of soft-issue injuries. Rex Ryan is so concerned that he's planning to double the stretching time at the beginning of practice, which will affect the 8 a.m. start time. (Stay tuned for changes.) They will stretch for 20 minutes instead of 10.

It also prompted Ryan to cut short a two-minute drill scheduled for the end of Monday's practice.

CB Darrelle Revis (hamstring), WR Jeremy Kerley (hamstring) and WR Chaz Schilens (groin) are among those dealing with various pulls, although Revis and Schilens practiced Monday.

Other highlights from Ryan's meeting with the media:

• Ryan said he's planning to use a clock during practice to speed up the quarterbacks' delivery. Tim Tebow, in particular, has been holding the ball too long. This isn't a novel idea; they used a clock last season for the QBs.

• Rookie LB Demario Davis (hamstring), activated from the PUP list, must participate in three padless practices before he can wears pads, per the league rules.

• Ryan talked about the maturation of QB Mark Sanchez: "He's a true pro. Four years into it, I think you expect it. You see it. I know the burning desire to win is there. There might be less messing around and a little more focus when you watch him now." Ryan said he wasn't surprised to hear that Sanchez, in an earlier interview, acknowledged he has studied the career arc of Eli Manning, who won his first Super Bowl in his fourth year.

• Ryan remained cagey on when he's planning to install the wildcat package. He said he's leaving that up to offensive coordinator Tony Sparano. So far, they haven't run any wildcat plays in camp.

• Embattled RT Wayne Hunter received some praise. "No doubt, I've been impressed with Wayne," Ryan said. Nevertheless, they traded for OT Jeff Otah, who remains on the PUP list. His status will be determined by Tuesday. If he doesn't pass a physical, the trade with the Panthers will be voided.

• Rookie DE Quinton Coples is having a quiet camp. Ryan suggested that the No. 1 pick is learned a number of different defensive fronts, which could be causing him to think too much. Coples has played end, 3-technique tackle, even a couple of plays at linebacker. "He's where I expected," Ryan said.
