Good data, thanks. It's why I love this board. I learn, and the dialogue is fun.
I knew Avila had starts at center but didn't know they wsere roughly equal to his LG starts. He seems to have settled in at LG, though, and loks ideal at the position after playing everywhere all over the line.
Still, from this distance I'd favor plugging him in at left guard and leaving him there.
We have two serviceable but young left tackles, presuming that old bugaboo of health, and solid guard play next to them in Avila would stabilize, elevate their play.
At center I'd have Avila as a third option, going off of what I know (which isn't much, with other rookie OLplayers I know next to nothing about) which means replacing him at left guard when we're dipping three-deep at center- and I hope we don't have to go there.
