I have never once said their is "basically no drop off between CJ/Trent and Nurk/Kanter". I don't know where you're getting your information from.
My whole point was that we have really good backups that we can still win a lot of games with if we play the right style of basketball. Not coincidentally, our best game in terms of style of play I'd say was the first Philly game, when we blew them out without Dame, CJ, and Nurkic, and when we weren't starting a true PG. Doesn't mean their was "little to no dropoff" from Dame to Rodney Hood, but it did show how playing a good style of basketball gives you a higher chance to win no matter what the personnel is, and playing such a style isn't dependent on personnel. We had some of the best ball movement all season in the game where we didn't have a point guard. And on another topic, did you see Kanter hedge and recover perfectly in the final minutes last night? Yes he was in a zone defensively but it didn't look like a guy who is incapable of hedging or trapping. That might be the easiest thing to have him do instead of sagging him onto his heels and letting guards drive straight at him.
