I'm not here to complain about how You(being EA) ruining a great game but honestly the game play is the same as it was 10 years ago a few things are different like Qb's seem to be extremely slow especially compared to their blitz 98 counterparts. with that being said NCAA Blitz would be a great game for these four reasons.
#1 120 different teams, with different types of players Scrambling QB or pocket passer, * back or a power back etc.
#2 Boss fights in Blitz gauntlet could be replaced by Mascot Matches.
#3 Would also be a good opportunity to Tweak the game play just a tad bit mostly with QB's speed.
#4 Would also bring More players who aren't fans of NFL games.
