I am agreeing with you. I made that very point (Indy rookie OL) in a few posts.
I don't see fixing the OL in FA. Maybe 1 improvement at OL in FA is realistic. It's more realistic to improve WR, LB, DL in FA than OL.
Too many teams need OL, too few quality FA available, lots of FA money.
My point was that it may mean Buffalo drafts OL in Rounds 1,2 or 3 and 'reach' for RT, C or G in the draft this year.
It seems we are both ok with that.
What is your favorite OL in rounds 1 and 2?
At #9 I like:
Jawaan Taylor OT
AJ Brown at WR
plenty of DL and Edge to like at 9
