I haven't seen any evidence or reports that Hill had a bad attitude during the pre-draft process. Whatever negatives he had were related to him being frustrated and vocal about not getting to play more, given he was the best Dlineman the Central Florida Knights had on their team. I'm not sure that many NFL executives will interpret an extreme desire to play as being necessarily negative.
I think he was a 2nd round pick because he didn't start (due to the change in coaching staff), and he played against lesser competition. And unlike many fans, I don't think there is a chance he would have lasted to pick 90. No chance at all. Even if half the NFL teams didn't like him, there were plenty enough teams that did like him that he would have been picked up soon after pick 58 if the Cowboys had not chosen him.
2 dts were taken between hill and #90.
dre'mont jone at #71
saunders at #84
look at how hill compares with these 2 physically.
hills weighs 310-330
jones is much smaller at 281 while saunders is 320 with shorter arms.
furthermore, hill is superior athletically to jones in all the important categories
and superior athletically to saunders in 3 out of 4 categories.
for the critical penetration stats for 3t, hill is vastly more explosive than both, even the smaller jones.
vertical jump (pure explosiveness) is
35" for hill while for 30.5" saunders and 31.5" for the much smaller jones.
broad jump (explosive + balance) is
115" for hill while 101" for saunders and 110" for much smaller jones
3 cone (pure agility) is 7.7 for hill while
7.57 for saunders and 7.71 for jones
shuttle (agility + explosion) is
4.38 for hill while 4.62 for saunders and 4.53 for jones
since some call saunder explosive, what does that make hill - rocket launched?
seriously doubt hill would have last until 90
