On many NFL teams, Lawrence Jackson would be a starting defensive end. It could eventually happen with the Lions. A student of the game, he makes things happen when he’s on the field. Here are three reasons Jackson is overlooked.

1. He arrived with little or no fanfare. It was during training camp preparing for the 2010 season when he was dealt to Detroit from Seattle where he didn’t fit with Pete Carroll’s plans. Arriving in the middle of camp is no way to make a name for yourself.

2. The Lions defensive line is filled with personalities and big names like Ndamukong Suh, Kyle Vanden Bosch and Cliff Avril. Starters just naturally get more attention. Jackson, a former first-round draft pick out of USC, has played in 22 games over the last two seasons but has yet to start.

3. He’s quiet, smart and engaging. He certainly doesn’t chase the spotlight. Those who pay attention, know just how valuable Lawrence Jackson is to the Lions.
