So if Quickley is the starting PG, the Raps will look like:
G: Quickley, Schroder
G: RJ Barrett, G Trent Jr
F: S Barnes, J McDaniels (the bad one)
F: P Siakam, O Porter / Boucher
C: Poeltl, (nobody)
They also have Gradey Dick and Thad Young. I imagine either Young or Siakam will play the backup center minutes. Maybe Otto Porter.
At least Quickley will allow them to stop playing Malachi Flynn who has been a major drag on their team for the last few years at backup PG.
Significant downgrade from OG Anunoby to RJ Barrett. Particularly for their outside shooting. Even less shooting at 2-5 now. RJ another one-on-one guy to clog the offense like Siakam and S Barnes. Anunoby more of an off ball guy who allowed others more room to operate. So that will hurt.
Quickley is a nice addition. Quickley will probably be more useful than RJ Barrett whether Quickley starts or is a 6th man. Quickley & Schroder can give them a nice 1-2 punch at PG which they have not had since Lowry left. They haven't had two capable lead guards since then. They will be a nice combination alongside one another as well as Lowry & VanVleet were. I like that guard combination better than Quickley and RJ.
G: Schroder
G: Quickley
Then you can use two of S Barnes, Siakam, RJ Barrett at forward alongside them.
Bad news for Gary Trent Jr though. His playin time will likely take a hit with Quickley and RJ coming in. Too bad. I like Trent. Good shooter / scorer. He could help someone. I'd like to see him leave Toronto. They do not value him there.
While OG to RJ is a downgrade, the addition of Quickley should make it a net positive for TOR overall. That looks a pretty solid team to me. That should play .500 ball.
