* Position battle at center heating up.
Richie Incognito has reportedly settled down after a bad first day of camp, and coaches are ready to rotate him and Brett Romberg at the center position now. In Incognito's defense, he has flipped from guard to center a lot in his career, which certainly will account for a slow start this year. If he's dialed in now, there should be a super competition at center.
* Defensive line depth takes another whack as Josh Thompson suffered the second significant injury of camp. He's out up to a month after tearing a plantar fascia. For Thompson's sake, let's hope he's not an injury settlement footnote in NFL history, because it seems like he has a little game. The Rams are beyond thin on the d-line right now, though, and had better hit the waiver wire.
