Says Tom Haberstroh of NBC Sports:

Would a reliable jumper help Simmons’ impact? Of course it would. But you could say that about a lot of players — most valuable ones, too.

The reigning MVP Giannis Antetokounmpo has shot 26.5 percent from downtown over the last five seasons. Russell Westbrook, another MVP, has shot above 30 percent on 3-pointers once in the last five seasons. Westbrook has made 216 more 3-pointers than Simmons has over the last two seasons, but he’s also missed 504 more 3-pointers than Simmons over the last two seasons. Those misses matter, too.

Taking more 3-pointers would probably be good both for Simmons’ development and the Sixers’ spacing. But excessive 3-point shooting from bad shooters can be just as hurtful to NBA offense. Yes, the offense can become clogged when it slows to the halfcourt and playoff teams can exploit that.

But even with the iffy shot and fit with Embiid, the Sixers were the eighth-best offense in the NBA. Not historic, but pretty darn good. And they were a bounce or two from the Eastern Conference Finals.
