we also have Bodine, who I think gave up very few sacks/pressures last year. We are okay on the interior. Crosby is a day 1 starter and like you said, a huge upgrade over Mills.
Although I just saw that Richie is threatening retirement. In which case, the pick here has to be Ragnow, a C/G. Day 1 starter also. Although, if Gory or Bodine can play G, perhaps you go Crosby due to the tremendous value of finding a starting OT this late in the draft. Crosby could also replace Richie.
I've confused myself now.
