Foul....if you have to

If a guy thats a little too big for you has a wide open layup, foul him quickly. It is easier to make a layup than a free throw. This is a personal favorite tip.

Dont settle for a jumpshot

Driving in is one of the most important parts of the game. You get easier shot which means more points(unless you cant make a layup).

Find your Strenghts

If you are great at one particular thing, exploit it. If you are a great shooter, keep shooting and getting better. You cant only get better through practice.
