I like his quickness. However, he looks pretty light in the ass. I don't see him breaking many tackles when he gets hit or wrapped up. I realize that's not his game. I like the role he's playing and his current contribution. I'm skeptical that he's a starting caliber RB and a reliable workhorse type RB. To be honest, Blackshear looked and looks better than Cook. I get the Cook hype because we all want him to be the reliable, dynamic, explosive RB that the Bills have lacked for years. However, we've been here done that with so many RBs. Cook's sample size is way too small to start declaring him the next Barry Sanders. Let's wait and see how he develops.
