I'm a big defensive first guy. However what we've seen so far this season it shows that Smart/Brown/Tatum + 2 bigs isn't working. On paper it should be elite defensively but in reality it isn't. And on the offensive end we definitely miss dynamic and playmaking. When Walker is inserted we get the dynamic, but not the necessary playmaking.
I believe stop playing two bigs, give Robert Williams more time and add depth can fix a lot of the defensive issues and the lack of shooting. What we need to obtain is a player who can be a real difference maker as a playmaker.
Ideally that would be a proven youngish player like Fox, Morant, SGA or even LaMelo Ball or Haliburton.
I'd imagine there's no reasonable option to get one of them, even if we tried hard, which I hope we do.
In the next tier we have guys like Lonzo Ball and Garland. The issue I have with Lonzo is whether he's enough of a scoring threat to run your offense through and Garland is a bad defender, with questionable upside on that end.
I think I wouldn't mind if we went after Lonzo Ball. If we take age out as a primary factor, then a name pops up who hasn't been mentioned a lot lately, but could be a surprisingly good fit: DeMar DeRozan.
We'd need to trade Walker (possibly to Orlando or New York) as is suggested in this thread. We then can still add depth with the TPE. A starting unit of DeRozan/Brown/Fournier???/Tatum/R.Williams + Smart as 6th man looks quite interesting.
DeRozan is 31, but is quietly having a very strong season. He averages 20/5/7 on .60 TS%, 4.4 AS/TO, just 23.9 usage and .20 WS/48. That is very impressive.
