It depends. Reach-in fouls are a little tricky to call, as refs will generally allow a small amount of contact...if you were to hit the player's arm and cause him to turn the ball over, that would be a definite reach-in. Basically, if he doesn't have trouble retaining his dribble, then you'll get away with the contact unless you keep reaching in excessively to try and pick-pocket the ball (hitting him a few times in the process).

depends on how far he extends his hands or arms to deflect or ward your hands. as long as he doesnt intrude your space in doing so it cant be considered a foul on his part
