To draft a rookie or not

After watching D-Mac at Arkansas run the wild hog(cat) and his pure speed I thought for sure a late pick would have been a smart move(never to the Raider effect into consideration), oh I was so wrong. So who do you guys think will be the rookie worth taking this year? I'm going out on a very risky limb and go with my teams pick Dez Bryant-WR, Romo is looking for another T.O. type and Dez could be the answer, now with two prime-time wideouts his QB numbers should be Brees like.
