From what I understand, the Acceleration rating has a lot more to do with actual speed in this years version. So don't get alarmed if you see Speed ratings lower than you think they should be. I just looked and Murray's Accel rating and it is 96. You will notice the speed difference when you play the game. Hope this helps.
which now props me to go look at the speed/accel/aglity rating for air force and colorado state... lol
