I don't quite agree. I would say in retrospect madden 10 was under under appreciated for what it started. Madden 11 was when Ian caved to external pressures. The extra point was removed, pro-tak removed, locomotion brought back ice skating players, etc. 12 was the year of franchise, but these guys work on multiyear plans. They knew when they released 12 that CCM was replacing it.
My point is that 12 just happened to be a better game than the others, but the philosophy of bringing stuff in to rip it out the next year was already back at Tiburon.
Bigfndeal made a good point as well. This Ian admits to mistakes and likes backbreaker physics over IE. Creative director Ian was very anti-euphoria and defended protak as superior. Maybe protak could've been improved, we will never know because it only lasted 1 game. IE is a major eyesore at the moment, and more or less a cheap imitation of physics, it's the worst of the three options.
