Right because Sullinger can never improve as a 3 point shooter so why should he try, after all 28 shots is a definitive sample. Furthermore spacing the floor from 3 point range has zero value I guess.
Right, all those other players who can't shoot threes are only in this situation because they haven't chucked it into oblivion in games.
I wonder why Garnett never spaced the floor all the way to the three. Oh, right, because he's a .280 career three-point shooter. Shame on his coaches for never forcing him to chuck 5 three pointers per game, imagine the improvement he may have had.
For the record, two-point shooting can improve too. And even if Sullinger ends up shooting .450 on long jumpers, and .300 from the three, which is a completely reasonable expectation, three pointers will still not be a better weapon for him.
