i don't know if he's at the top of my list but Matt Hasselback sure came back great from that pro bowl year he had out of no where
As far as underrated from the skins I'd have to say my choice would be Cooley. We as skins fans know who he is but it doesn't seem to register with those outside of that and I think that has to do with the fact that he's not really counted as a TE but instead a RB/FB even in fantasy football leagues. As far as overreated skin, I'd have to say its Samuels for me especially with the price tag he carries.
