Presuming Moe and one more of Ibi, Brooks, Davis is gone, I would rather add a big. Those are tougher to come by than wings and 2 guards so it’s not like I’m waiting for that to happen… but if Ibi and Brooks are both about to leave then yes absolutely adding a shooting guard makes sense. If only one of them is gone + Moe, I think the backup guard depth is fine.
PG: Simpson (30)
SG: Poole (30)
SF: Matthews (30)
PF: Livers (25)
C: Teske (25)
That leaves 35 minutes at the backup 2-4 spots to split between Iggy and Johns, if you could slide Matthews down to the 2 or play Iggy there somehow. I really envision them being good enough to need those minutes.
Then you still have Dejulius at the PG backup. One of Brooks or Ibi or Nunez for any scrap 2 guard minutes. Davis/Castleton at the 5.
But if JB plans on Livers/Johns both getting real run at the 5 spot then I guess I could see a need with Mooney. I’m not a believer that that’s going to happen though and I like both of their games as wings a lot more. If we’re seriously looking into this, my gut feeling is that both Watson and Brooks are on the way out.
