I've always taken Contact and Power pretty literally and thought of vL and vR as being more about the hitter's likelihood to drive the ball (I think this was mentioned in a dev chat once). How does it work for you when you're evaluating free agents or the draft class though. I'll invent two players:
Player A - Contact - 80, Power - 85, vL - 60, vR - 60
Player B - Contact - 70, Power - 70, vL - 75, vR - 75
Assuming all else is equal, who are you taking? I think it'd be player A for me, though if I felt like his vL and vR might not crack the 60s, I'm not so sure.
