LOL, that is first off insane as I have seen the #1 WR be only 5-10 and would never be anything but a slot. It doesn't help anything in long run as there are plenty of crossing routes for the outside WR as well which at 99 speed only like 2 or 3 CBs in the game can stay with him. hell, its actually easier to run a clear out for the outside WR then the inside. you just call a play where the outside guy crosses and have everyone else go the other direction... "CLEAROUT". at least a fast guy in the middle only has half a field to work with and the D gets to use the sidelines.
In real life defenses play special speed guys differently like Florida game planned for Teddy Ginn but the CPU doesn't even recognize play calling or learn from .0001 seconds earlier so its night and day difference. I am thinking a top end speed of 94 is probably a must on offense. I believe A- top speed is 94 so we could just say A- speed or something like that.
