I really think people are putting too much emphasis on the ability to shoot the three at the shooting guard position. Yes it's nice, but Memphis and Indiana got to the conference finals without it (and since we're talking about them in this thread, the 03-04 Pistons won the title without it). Lance Stephenson was OK shooting 33% on 62 makes, and Tony Allen was terrible and shot 13% on 3 makes. Neither team really has elite 3 point shooting at any other position (the closest to that would be George on the Pacers, who shot 36% on 6 attempts per game... more volume than efficiency really). Both Memphis and Indiana made less three pointers per game than we did (16th and 30th in the league in makes, we were 15th), and both teams were in the bottom 1/3 of the league in three point shooting percentage.
What I'd like to see with DeMar is have him used more off-ball coming off screens, but I'd like those screens to be set lower like what Detroit did with Rip. It'd be nice to see more of his mid-range Js come from 10-16 feet rather than 16-23 feet. That would improve his efficiency, increase his chances of getting fouled and also improve our chances of getting a rebound off a miss.
