Others here have said most everything I would have, but I did have this to add about our OL recruiting.
I wonder how many of those who point to Jump (he's the 260 OL recruit) or Mackeehan or, for that matter, Clark and Quinney last year ever listened to Sewak and West talking about them or looked at their films. Sewak and West were quite straightforward about why we recruited them: they played both OL and DL. This is especially the case with Jump; most of his film is with him at DE and that's where other schools looked at him. We liked him for OL at Tech because DLs have to a) learn to keep their pads down and b) are normally faster and more flexible then exclusively OL recruits.
It isn't that we don't look at big guys if they can move; we recruited both Shamire and Hall (too bad about him) because they were humongous and had quick feet. But the kind of OL we want isn't a zone blocker who pushes and dances. We want OLs who will keep low, play fast, and hit people. It's a plus if they also played in a TO offense (hence Mackeehan), but the main thing we want is, as Coach Gaithers said, linemen who are "agile, mobile, and hostile."
If this means we pass on the occasional lard bucket, I'm all for it.
