Its not about a NT philosophy its about discussing the best training regimes for players and a team overall but since you seem to have already mastered it perhaps you could join up at the forums and share your wisdom with us?
A few things I'm curious on:
1) What evidence have you seen that shows Driving is useful for a SF but useless for a guard. Most would argue that its either completely useless or vice versa.
2) Have you read that driving is a bigger factor in a guards inside shooting over IS itself? (This was posted by BB Charles)
As far as the cost of handling and driving, you are partially correct in that sometimes driving is more expansive, but some times it's the other way around.
3) I said Handling was more expensive in almost every case and thats most likely due to its dual functionality at decreasing turnovers as well as increasing your players steals on defense. But you would prefer a player with 13 Handling 5 Driving over a player with 9 HA 9 Dri?
