Yup, it's why i feel they're basically Boston 2.0 in the making, i actually forgot all about Dort and was thinking of Caruso as their "Jrue". I don't even think having Holmgren at the 5 is bad, if not for the other 4 guys (SGA/JW/AC/Dort) all being 6'6, 6'5, 6'4, and 6'3.
Boston can get away with KP at the 5 because Tatum himself is 6'8/6'9, which means any offensively circumstantial PF like Aaron Gordon can't exploit that matchup. So ideally I feel they need 2 pieces that can interchange from starting or off the bench: (1) a floor spacing big (possibly Hartenstein) and (2) a stretch 4.
That way you can have Chet interchange between the 4 or 5, and still have size (pause) when he's on the bench.
