True on both points. OL becomes an increasingly technique-driven set of positions the higher the level of competition. I think both Dunlap and Faalele have very bright futures, but it takes more than brute strength to succeed as an OL in the FCS. I'll let Warinner and Fleck make the call on whether or not they are ready, but there's no harm in red-shirting them.
As for Federer, great baseline game. Oh, it's Feder. Hey, more OL depth is always welcome on this squad.
Someone started another thread about Zo Craighton transferring. That would open up a slot (I believe).
