I think Allen "complains" a lot to the refs after he gets hit when sliding or "roughed" (and by complaining, he usually looks at them and puts his hands up (aside from the personal foul against the Rams for yelling at the refs lol)). Seems he might not get some calls because of his size maybe (big strapping lad and maybe a thought from the refs of "hey, if you're going to run, that's what happens"). Not sure. I remember there was that time a few years back where Ed Biceps said to Cam Newton something to the effect of "you're not old enough to get that call" (obviously, not size related, but still a weird, biased view from a ref).
