That sounds like yet another OL experiment, and way too dicey to use a 1st round pick on. And I for one am tired of seeing Oher see-saw between RT and LT. He needs to stay on the right and the only time he should EVER go back to LT is in a dire emergency. Honestly, I'd rather see McKinnie back for another year (holds nose). And we all know McKinnie's question marks.
If you're going to gamble then use a later pick, not a first rounder.
Hey, if Castillo really likes a guy and convinces Oz & Co. that a guy is worthy of being picked there, I'm not gonna complain.
I'm also not of the opinion that Oher can't improve at LT with some help from Castillo.
