Avg/HR/RBI was nice becuase it provided a balance between AVG Hitters and Power Hitters.
Basketball is a bit weird cause of how the game is played.
I think Points, Rebounds, Assists and Steals+Blocks is fun maybe add 3P% to add some fun. Obviously big men help you in the Boards/Blocks but they also don't hurt you in 3P% because they don't take many. Maybe set that you have to hit 200+ 3PA over the course of the season so you can't just load up on C's and PF's.
