"able to"
Being able to rotate 3 guys with mediocre or worse play is not the kind of depth I'm interested in.
Peters has been the best, and he's been mediocre. McGovern and Farniok have played poorly, and Biadasz hasn't been much better.
Peters probably ramps up to a decent to good LG.
I expected better with McGovern, and he has been better in previous years. But this year he's been poor, as has been Farniok, and they're our depth for the entire oline, whether they're filling in for the interior oline, or backfilling the oline if a T goes down and we move Peters out.
