I think that Williams(size /speed), Davis(speed), Hawk(speed, instincts) and maybe even Cutler(extremely strong arm, benches over 400lb) fall into this category. Young might be too, but probably too much of a risk. D'Brick does not qualify as a freak! His measurables = A. Jones. Look it up if you don't believe me. If he weighed 340 and was a devasting run blocker he would be a freak. He's just an excellent pass blocking LT. We can get starters for the o-line at 29 or later.
First: is this thread really needed when there are a million other threads discussing these players Second: Being an OL is not all about size or O'Callaghan would be one of the first taken.
The aforementioned guys are not JUST work out warriors. They are guys that performed at top level AND have incredible physical attributes. There are other lineman in this draft that with some time will be just as good or better than D'Brick.
