If he doesn’t have it by now, what good reason is there to think he ever will?
What could this guy have been doing all last year? When I go into an empty gym, I put up shots. And shots. And more shots. Yeah I’ll get in handling/post moves, but still, you put up shots.
I don’t practice barreling down the lane absorbing imaginary contact on an imaginary fast break to make a hoop. This guy had an entire year to work on his shot and instead went a whole season without hitting a three.
Maybe he simply doesn’t have the mechanics to be a shooter. We’ve all been waiting for Marcus to clean up his shot and it’s not happening. But at least we can see him working on it and taking them. Sure we cringe at most of them but occasionally we get a 7-trey game out of nowhere. Simmons has zero desire (or willingness) to even look at the rim outside of the paint.
Oh an his defense is pretty bad too.
