My perception has been that Jeff Capel has not really reigned in many of his players. He seems to have a philosophy of take the best available shot (even if that means a lower precentage shooter is taking the higher percentage shot) rather than have the best shooters take the bulk of the shots (even if it means a slightly lower precentage shot by a high percentage shooter) (Sampson seemed to be more of this later mindset).
I don't know how many 3s we will see Tiny take but I suspect Capel will encourage him to take shots that he can consistently hit and if a 3 is one of those shots, I suspect he will have the green light.
