The backcourt will be improved, IMHO.
Quickley replaces Gilgeous-Alexander. I think Quickley will be an improvement.
Johnson replaces Knox. That's a push.
Herro replaces Diallo. Diallo is the better talent and better athlete, but Herro is the better shooter and probably the better team player. I am not giving up on Diallo, but right now losing Diallo looks like addition by subtraction, based on Diallo's recent play.
Green will have a year under his belt. Should really make strides this summer.
Baker gives us an extra guard. If he comes back 100% healthy, maybe he pushes Herro out of the rotation.
The frontcourt should be better.
Washington, Richards, Gabriel, and Killeya-Jones should all improve.
8-man rotation:
Starters
G Green
G Quickley
G Johnson
F Washington
F Richards
Key Reserves
G Herro
F Gabriel
F Killeya-Jones
Things change if (when) we add another player or two, but as is we will be very good.
Seven 5-stars and a 4-star. Two Juniors, three Sophomores, and three Freshmen. Good balance of talent and experience. Good depth as well.
Could see us add another player or two.
