According to an article at NCAA.com, there were 325 players from outside the Power 5 on opening day NFL rosters this year. Even if you take out independents (because a majority are probably Notre Dame), that still leaves close to 300 non-P5 players. Now, if the AAF has more G5 players than P5 players, then that's likely a problem. I suspect that is not the case, though.
