This would at least let us know if someone was going to be totally uncovered before we get owned by running a certain play in a game. I hate picking a play that should have enough man coverage for each receiver, then find one or two receivers are double covered and the other one or two are left wide open.
Most of the coverages, zone and man, are ridiculously poorly coded. The advantage to this is not really knowing whether your SS is covering their TE on a certain play, but if they don't have a TE, will that SS now go and cover that 3rd or 4th WR?
