Through six games we've seen a complete resume from Devin Bush. As a rookie, you're expected to make mistakes. Bush did. He was mentally wrong on a number of occasions through the Steelers' first four weeks - blowing coverage, being in the wrong spot, the usual rookie mishaps. Since then, he's been the best linebacker in Pittsburgh. In a group of T.J. Watt, a breakout Bud Dupree, and Vince Williams, Bush is playing better than anyone. His interception, fumble recovery and touchdown ended the Chargers' hopes of winning before the end of the first quarter. There are other defensive rookies playing well this season, but outside of maybe one, Devin Bush is the midseason Defensive Rookie of the Year.
