I think we made the right choice. Its much harder to find a dominant LT in this league than a Dominant rusher. Add in the fact that Tyron is a year and a half younger and we had one of the worst OLs in the league at the time.
I didn't say he was five but in the top five. I think it's difficult at times to say who is 1,2,...5 although at times 1 or 2 are clearly better than the best of the rest. Thomas is the best. The improvement of Collins will make it easier on Smith. But for whatever reason he gets rocked at times and even beat outside on occasion.
In no order:
Thomas
Smith
Armstead
Staley
Williams
Whitworth
Peters
a few others
