Sure, the Ravens have protected their offensive line at times with all the short passes and check-downs. And yes, the Ravens have used their tight ends a ton to help out in run blocking. There have been some games in which the offensive line has struggled, and the Steelers, with Cameron Heyward and Stephon Tuitt inside, provide another big test Sunday. To this point, though, you’d have to say that the offensive line has exceeded expectations and you can’t say that about many other Ravens position groups. D’Alessandris and Greg Roman deserve a lot of credit.
