Lions DE Ronnell Lewis played on one defensive snap as a rookie.
Lewis, a fourth-round rookie out of Oklahoma, found himself buried behind the Lions' impressive defensive line depth. That could change in 2013 with Cliff Avril and Lawrence Jackson set to become unrestricted free agents. "I think [Lewis] is going to be a factor going forward," GM Martin Mayhew said. "I think he'll be a good rotational defensive end/special-teams player for us. He's got ability, without question."
