In practice and all other instances. Because I practiced, played, watched film with them I had a pretty good idea what was going on. The spot was handed to a transfer from a d1 school, but he hurt himself lifting on testing day (the one day a year he actually lifted) giving the other guy a chance. This guy IMO ended up being the most consistent OL man on a very, very good oline at UND. I think he graded out the best of all starters in over half the games and this group had several professional football players in it.
