I think Madden could be more interesting if ratings were hidden and all we had to go by was the Read and React system. Going from my understanding that it's based off of the current player ratings (and possibly assigning players to tiers, a la All Pro, but there could be a different way to differentiate two players with the same traits but one is an All Pro and another isn't), it'd have to give a little more leeway than only classifying the elite players at a particular skill to allow for more players to be given traits, but I've always wanted to play a Madden franchise where I didn't know exactly how good a player was at any given time. Players without any of the Read and React traits would have some sort of baseline attribute levels and then one of the various types of players that the PS2/XBOX Maddens use to have (Scrambler QB vs Pocket Passer QB, Coverage Linebacker vs Pass Rushing Linebacker vs Run Coverage Linebacker, etc.)
It'd simple things down and help add to the chess match dynamic that EA is trying to create with Read and React.
