I find the RG position is often standing like a dud with nobody to block, which naturally means more vision = bigger blocking radius = more likely to pick up a second level block or a blitzer. I'd go to 60 for a RG. 48 + some extra training for the others. Went to 60 on my C for lack of a better option, and special teams blocking, but the value of that decision is marginal at best
my center has 63 vision (got a run block piece that was +2 vision)...lack of a better option and it was cheaper than third capping agility. O-line gets boring and intriguing at the same time when you hit level 45.
We're getting a new tab next to box score, play by play, that displays every player's # of plays, energy, and end-game morale, as long as you're a GM of the team you can view it.
