Most people don't understand this concept. NFL players ARE faster than college players but the difference between a fast NFL player and a slow one is not that big. The difference between a fast college player and a slow one can be huge. That gives the college game the perception that it's faster sometimes which is why I agree that NCAA should play fast. Fast (and sometimes small) RBs can excel in NCAA but rarely do in the NFL since it's more of a power running league.
I personally found the Slow speed on Madden really slow. But options makes everyone happy (offline at least).
