The Lions have worked seventh-round pick Johnny Culbreath strictly at offensive tackle in training camp. A freak athlete for his size at 6'6/322 with a 4.92 forty, Culbreath is being given a look as Jeff Backus' possible eventual replacement. While that's a major long shot, Culbreath has "flashed everything he needs to do to be in the NFL," said coach Jim Schwartz. He'll likely spend 2011 on the practice squad.
