We can criticize the personnel precisely because they seem incapable of doing fundamental basketball things. It is not normally the job of an NBA head coach to teach veterans like Whiteside, Baze, Melo, CJ and Dame how to box out, or how to rotate. Yeah there are some young guys getting minutes and you expect them to screw up here and there, but the fact that all these vets seem to have no clue is way more than just a coaching problem it's a personnel problem. They basically have a shot blocker in Hassan, 2 guys who play defense about once every 10 possessions, one guy who's gotten better but still isn't a great defender, and a guy who gambles a ton, the personnel is just not one for a good defense. I've always hated Stott's defensive schemes, but it's so bad this year, it's literally the worst I think I've ever seen the Blazers play defense and that's saying a lot... The players deserve a lot of blame for that as does the coach, because at some point when you're ball watching, or swinging your arms at guys instead of moving your feet, when they pass to Harris in the corner and NO ONE moves they all just turn around and go oh guess he's gonna shoot that TWICE, that isn't just the coach, that's players who look to have given up on defense. Yeah, a new coach may come in and yell at them good for not playing a lick of defense but at the end of the day if you're stuck with a bunch of guys who don't care about defense or just aren't good at it you'll get the results of crappy defense. The coach deserves criticism for schemes, the players deserve criticism for either a.) not knowing the fundamentals or b.) being unwilling to actually do them.
Lionel Hollins coached the grit n grind grizzlies went to brooklyn and couldn't get them to guard anyone. Pop coached some of the best defenses ever and can't get this group in SAS to play good defense. A change of coaching may help, it may not, I know for sure the personnel is somewhat to blame.
