What we learned on Day 27

FLORHAM PARK, N.J. -- Observations from the sideline:

1. Run, Joey, Run: Joe McKnight, he of the failed conditioning test/dehydration/migraine/traffic arrest/head injury, returned to full practice and looked good. Perhaps sensing his roster spot could be in jeopardy, he ran with purpose and determination. He told reporters he expects to play Saturday night against the Giants in what would be his preseason debut. You'd have to expect his A-game. Maybe his recent adversity has served as a wake-up call for McKnight, whose inconsistency has been maddening for coaches.

2. Dee backs off: Top pick Dee Milliner took some heat for his passive coverage against the Jaguars, but it appears he was playing cautiously because of a pulled calf muscle. It happened up in Cortland, but he tried to play through it. On Tuesday, he was held out of practice, with Rex Ryan noting the calf didn't seem to be improving. Smart move, backing him off. Milliner is a vital part on the rebuilt defense and the Jets can't afford to lose him for an extended time.

3. When you have two free safeties, you have none: The Jets can't make up their mind -- Antonio Allen or Jaiquawn Jarrett? -- so they'll let the free-safety competition go for another two games. Allen will start Saturday against the Giants, Jarrett the following Thursday against the Eagles. I wouldn't get too hung up on the outcome of the competition, because I have a feeling Ryan will be using a lot of one-safety, three-corner packages, utilizing Kyle Wilson in a safety-type role.
