Also, keep in mind that these are guidelines for a generic player who is likely to be a prominent presence in those leagues, but your situation may demand that they specialize in some areas to maintain roster balance. You might end up with a guy who specializes more in Driving than JS or something like that.
Build the players you want to play with.
Hopefully some other people will pop up with some advice that I left out, or be able to expand on some alternatives to what I've said!
