Jets can't stop chasing backfield help

That Joe McKnight draft pick keeps looking worse and worse for the New York Jets.

Last year, the Jets drafted McKnight out of USC in the fourth round. McKnight was throwing up from the moment he got on an NFL practice field and had trouble finding his way for much of the season.

McKnight's presence on the roster eventually led the Jets to waive Danny Woodhead, and New England Patriots fans couldn't be more thankful for that.

The Jets on Saturday afternoon felt compelled to draft another running back, taking Louisville's Bilal Powell in the fourth round.

The move doesn't seem to be good news for Shonn Greene. Although it won't put Greene's job in jeopardy, you can't help but feel the Jets are uneasy in the backfield.

Since the Jets moved up to draft Greene in the third round two years ago, they've shown reluctance to let him shoulder the load. They signed LaDainian Tomlinson last year, drafted McKnight and now have drafted another runner.

Powell rushed for 1,405 yards and 11 touchdowns. He added 18 receptions for 158 yards and three touchdowns.
