The St. Louis Rams' biggest surprise in the 2012 NFL Draft so far came in Round 2, when, with their third pick of the round, they selected off-the-radar running back Isaiah Pead. I was as unaware of his existence as you might be now. With that in mind, here's Isaiah Pead in 200 words (or less.)

He has a Twitter, which is, excellently enough, @iPead; he was WalterFootball's sixth-rated running back, which left some draft pundits calling this an overdraft, but their identification of him as having "an astute ability to identify blitzers" probably excites Sam Bradford; Mocking the Draft likes his receiving ability, and others have suggested he could, at times, line up as a wide receiver; he is the kind of running back who will get called shifty a lot.

That's all code for, "This guy will back up Steven Jackson without scaring Steven Jackson, and help Sam Bradford if he catches on enough as a running back." Not a terrible haul, but not the kind of upside you asssociate with the average middle-of-the-second-round pick.
