it's like I keep saying, though...LMA is a threat. Lining up at 18 feet to receive the ball, or running pick-and-pops, isn't the problem. Taking the shot if he's wide open or against a smaller defender isn't the problem. Taking contested shots (or worse, contested shots against a double-team) does nothing more or less to help "spacing" or "freedom to work the offense". The defenders are already keyed on LMA, so someone's going to have a better/easier/more efficient shot.
Bosh makes his 10-24' jumpers, contested or otherwise, at a 44% clip. Scola's at 45%. Dirk's is 47%. The others use a 3point shot (like LMA is this year) to increase spacing and/or pull out defenders even more. LMA's at 41%. Even K*be's at 43%. (all numbers career, but for guys long enough in the league for the curves to smooth out)
