Detmer, Nelson and other QB's that don't exactly have strong arms, had to find other ways to get more time in the pocket. I'm not saying Detmer's arm was like Nelsons...not at all, but they both had to buy time and were able to do this...Detmer a master of course and we have the Miami highlights to prove it (as well as others).
For some reason, and maybe it was related to Highschool being too easy for him, or maybe just because of his ridiculous speed, Hill has (in DT's opinion) average pocket awareness. For a guy w/ his speed, his athleticism, he gets sacked a lot when he shouldn't. It seems mental to me, but it's a weakness for sure, and I think it contributes to his accuracy issues.
Yes, I'm stating that THill has mediocre pocket awareness...and it's strange.
