" I disagree on Fournier. And even with Kemba and Smart that is still happening with quick PGs (way too often). You want length and switchable guys to stop quick guards who iso or use pick and rolls for better rotations and coverage. So long as all the players move well and feature size or freak athleticism it will work."
I also agree and that is why I think Lonzo Ball would be a better fit. His current contract is less than Fourniers and his projected contract is around the ballpark Ball will be in for future the future contract $17-20 mil range. If acquired by trade, I believe bird rights would allow the Celtics to go over the salary cap to resign. Ball is a pass-first, long PG who and defend multiple positions, rebounds, who has approved his 3pt shooting 38.5% and does not need to be a high volume shooter-which is very important with Tatum and Brown on the team. Add him and Gordon and give our next two/three years of what should be late first round picks and anyone but Tatum, Brown, R. Williams to do it...I'd love to keep Smart too, but don't think it is likely. With this roster, the Celtics would be young enough to lose out in 2-3 years of drafting in the first round.
