I'm preparing to get laughed at for this, but my predictions on this Blog for the past year and a half have been pretty darn good, so I'm prepared to take an L on this long shot:
I'm not advocating for this (yet), as I think it's remote, but within the realm of possibility that the C's starters could be better overall with a big, impactful center like Baynes.
Starting Baynes wouldn't maximize the talent on the court at the beginning of games, but it might maximize the talent that plays on both units and allow for a better blend of O and D.
Hayward has looked rusty, but still, the starters haven't looked good. Brown and Irving have played well but Tatum and Hayward haven't and we need to see how they co-exist.
We know that last year's starters with Baynes was great defensively and ok offensively. I also think Robert Williams looks better than Theis did last year, and should be in the rotation.
So if Baynes started, who'd sit?
Right now, Hayward looks rusty, and last year's starters looked good, so he's an option.
But I think the nuanced choice is Tatum as 6th man. When Hayward returns to form he should be better and more versatile than Tatum for a year or two, so he deserves to start. IMO Smart and Rozier can be the 2 ballhandlers on BWA (Smart a playmaker, Rozier mainly a scorer).
Hayward's playmaking is needed with the starters, where he & Kyrie are the 2 ballhandlers (GH a playmaker + scorer, Kyrie mainly a scorer). GH should be able to score at least as well as Tatum when he's back to form, but this way both units would have 2 true ballhandlers. Also, both units get a legit rebounding and defensive center in Baynes + Williams, and a dynamic scoring 2 way wing in Hayward and Tatum. As 6th man, Tatum could still play plenty with the starters and with BWA he'd be the main man on offense, flanked by Rozier and Morris. They'd all look to score. Smart could focus on playing D and getting Tatum and Williams the ball.
So is KI-JB-JT-GH-Al more talented than KI-JB-GH-Al-AB? Yeah. But does #1 + Rozier / Smart / Morris / Theis / Baynes beat #2 + Rozier / Smart / Tatum / Morris / Williams?
I mean, it probably does. Having the most talent start is probably best. But I don't think we know for sure. I don't think Brad knows for sure. The team has played very poorly in preseason and the starters have been the worst. Last year, our starters were our best asset and we had Baynes in there anchoring the D. The roster balance of #2 could be really key.
