Bruce Gradkowski looking at his career, has only improved as a player. Most list his weaknesses as he's too short and too injury prone, I looked a little further into these claims to see if I could dispell them.
During my research I found that despite his small stature, Bruce is listed as 220, 10 pounds lighter than Jason and the same weight as Darren McFadden who pounded the rock 30 times this past Sunday ( I note Darren McFadden is probably a bad person to evoke when drawing comparisons of injury resilience, but you get my point). He started every game for Toledo after being named the starter.
When he went to Tampa Bay to start his career, he was never put out of a game through injury, only through being benched, in his rookie season. During that first season he was 3-8 with one of those wins coming against Jason Campbell and the Washington Redskins, Jason himself making his first ever NFL debut that game.
On November 22, 2009, Gradkowski made his first start for the Oakland Raiders. In this game he threw 2 touchdowns, matching Jamarcus Russel's total for the season to that point. After a further two good games, one against a strong Dallas defence, Bruce had his first ever serious injury (from what my research could find) with a partially torn MCL in both knees, an injury which usually comes from an awkward hit. Get-it-done-kowski through 2 quarters of play has as many Touchdowns as Jason through 6, much like our old friend Jamarcus Russel. So raider nation, who says my main man gets the keys to the car?
