Brian Westbrook doesn't throw HB passes, why does the game need to figure out who worse at throwing the football ? Players that haven't done something in the NFL should have a N/A by that rating. If you try to get them to do whatever that something is, they should fail miserably. Now if a player who hasn't done that something, all of a sudden does it(in real life), that's what roster updates are for. My point is, the game doesn't need to figure how much worse a player is at something than another player, especially when you consider the fact that there is no data to determine that.
This is all just speculation. I don't see the need for STR rating for a olineman when you have a strength rating for pass blocking and run blocking. RBF could effect how good a defender is at getting in position to make a block and how long he can hold the block , where as RBS would determine if he blows his lineman 3 yards of the line, pancakes him or gets very little push at all.
If RTE running is for KNOWING where to be and when to be there, then what role does awareness have ? I would think that awareness would determine if a WR is where he's supposed to be, when he's supposed to be there. RTE running controls how fast the a WR comes in and out of his cuts.
