I get what you're saying but guessing who "they" are is just that, guessing. We don't know who that is supposed to be. Since the article says it's being done after practice I'm not going to get worked up over it. Our rebounding sucks but we don't know what they're devoting time to during practice. That could have something to do with why Ayton decides to practice his 3pt shooting afterwards. If he's working on rebounding throughout or towards the end then maybe he just wants a break from that, we don't know. I think the author could have expressed that part a lot better though because it does raise some questions. I'll quote it again just for reference and to keep anyone else from having to click on the article,
That is too vague. I'll try reaching out to the author on Twitter to see if he'll clarify who the "they" are in that case but I don't think it's that important to how the Suns are right now. I would like to know because I'd like to know who on the coaching staff, or on the team, is trying to help him develop a 3pt shot.
Ultimately our defensive rebounding needs to improve more than our offensive, IMO. We give up too many 2nd chance points and that's a recipe for losses on it's own. If Ayton grabbed a few extra offensive rebounds it would help us keep things closer or get some easy points but working on his 3pt shot isn't useless if he can develop it well enough to start running a pick & pop with Booker, Tyler Johnson, Jackson, or Crawford instead of just rolling. That would actually add a new element to our offensive that might help keep opposing defenses on their toes and make it harder for them to predict what we're doing offensively.
