I don't remember the Texans or Chiefs being all that when Pollard was there but I might be mistaken. The Ravens have had a good D for what seems like the entire decade so I doubt Pollard was the key to that. See that's the thing about coaching and leadership, you can believe that a guy is having an impact on how others play but it's really hard to quantify it. Like if we credit Pollard with raising Casey's level of play, do we then blame him for Brown and Ayers falling off? You can't really have it both ways. It's safer (IMO) to assume that his ON the field impact on the physical aspects of other players has been minimal and that guys are simply playing up to their current talent level, not necessarily their potential. A guy who makes a big hit now and again does energize a team but that burst is temporary and is only maintained when others around him take the inspiration and run with it. What good is a big hit or ra-ra speech if you get your ass kicked on the next play?
