CORTLAND, N.Y. - Mike Goodson is nowhere to be found. Chris Ivory has yet to carry the football in team drills. And Joe McKnight can't consistently stay on the field.
But when asked Friday about the team's lack of depth at running back, Jets coach Rex Ryan essentially said: That's news to me.

"I haven't really noticed per se," he said, noting the training camp signing of Chad Spann and the use of fullbacks Lex Hilliard and Tommy Bohanon in one-back sets. "When Chris comes back, obviously, you'll feel a little bit better about our depth."
McKnight walked off the field with head trainer John Mellody after getting shaken up on a play. He did not return and Ryan provided no details on the injury.
"I haven't really talked to the trainers yet," he said. "I really don't want to speculate, but I think if it was something serious, I'm sure I would have been told."
Freeman carted off
Rookie center Dalton Freeman was carted off the field after suffering what appeared to be a serious leg injury. The former Clemson center, who was having an impressive camp, was caught at the bottom of a pile during goal-line drills.
Ryan later defended his decision to practice live tackling for the first time in goal-line and short-yardage situations.
"There's only one way to practice it and that's to go full speed," he said. "You can't get the reps. You may say well, you get it in the preseason. There's no guarantee."
Ryan, Mark Sanchez and Geno Smith all agreed: The defense had the upper hand during goal-line drills but the offense had the edge in short-yardage drills . . . First-round CB Dee Milliner (shoulder) saw increased reps, including team drills. Fellow first-round pick DL Sheldon Richardson (root canal) returned . . . Ryan praised LB Ricky Sapp -- "[He] jumped out at me. Probably had four or five sacks," he said -- and WR Stephen Hill, who missed Thursday's practice with an illness. Ryan also raved about the fiery "presence" of G Willie Colon, a Hofstra product . . . WRs Titus Ryan and Marcus Davis did not practice, along with veterans Braylon Edwards and Kellen Winslow Jr.
