Alexander has better consistency than any back int he league right now, he's been doing it better, longer, without getting hurt, than anyone in the league. Priest has had 3 good years, Ahman has had 1 or 2 around injuries, and LT hasn't been around as long as Shaun.
I'm a big Alexander supporter. he's a nice safe top-RB pick.
of course, he's overdue for a big injury, so maybe you should just ignore me.
