For perspective, the difference between shooting 87% this season and 90% like last season is 3 FTs per 100. Basically, Ray is missing one more FT for every 33 that he takes.
I don't think that's a significant difference. In fact, had he hit those two FTs last night, he'd be at 89% right now, which is virtually identical to last season. All things considered, I still want Ray at the line when the game is on the line.
