Noel won't last forever. Maybe he can teach Neemias a thing or two.
I think it would have to be during training camp. As others have mentioned, I think this is essentially a battle between Noel and Queta for one roster spot. As it stands today, here's who's under contract with the Kings:
C Sabonis/Len/Noel/Queta
PF Barnes/Lyles/Vezenkov
SF Murray/Edwards
SG Huerter/Monk/Duarte/Jones
PG Fox/Monk
Plus Keon Ellis and Jalen Slawson on two way deals (one two way slot still available) and Jake Stephens on and Exhibit 10 deal.
It could be possible that McNair really values depth at center after it was a weakness last season (and especially after Sabonis' avuncular fracture and playoff injuries) and that he expects Duarte or Jones (or Huerter at times) to flex to a forward spot while Monk acts as the 3rd string PG.
But I just don't see it. Even if they sign Ford to the 3rd two way, the roster just isn't balanced. To get minutes for both Lyles and Sasha I think Trey needs to play some smallball 5. And McNair has shown that (1) he likes having some roster flexibility and (2) likes to use that flexibility to take low risk gambles on long, athletic wings.
I hope Queta flashes in training camp and solidifies his spot. But if he doesn't, I think he'll be cut (I don't know if he can then be signed to the last two way spot or not - or if it even makes sense to do so) and Noel will be the 3rd string center this season. Either way, unless Len struggles and/or they don't use a Lyles/Vezenkov frontcourt, whichever guy survives camp will likely only play due to injury or to occasionally give a different look behind Sabonis.
