Very Few.
Grassu has been on 6 teams in 5 seasons
Elflein is on his second team in 3 seasons
Cushenberry was just plain bad.
Kelly, Price and Bradbury were all first round picks, which, since we lack a #1 pick, makes them hard to apply to this discussion. Bradbury was drafted to replace Elflein.
Cole and McCoy were hits in the second and 3rd round.
Not saying it's impossible, but the odds of finding a rookie OC of quality are going to be low.
