As you might recall, the Lions finished up offseason workouts with five veterans -- Daniel Bullocks, Gerald Alexander, Kalvin Pearson, Marquand Manuel and Stuart Schweigert -- competing with rookie and Louis Delmas. Alexander was traded to Jacksonville to reduce the glut, Bullocks suffered a re-occurrence of an old knee injury and Manuel has been limited by injuries in training camp. Delmas and Pearson have been working with the first team, but Pearson has struggled and Delmas is still learning the NFL game.
Lions general manager Martin Mayhew has been rolling veterans in and out of his building for what amounts to extended tryouts. So I can’t say that Simpson is going to challenge Pearson for his starting job. But it’s pretty clear the Lions depth at the position has dissipated considerably.
