The two things that were pretty apparent
1. Kornet is predictably awful. Orlando were literally licking their chops whenever he was in the game and just attacked him all game long. He's fine as like a 4th big/garbage time guy but definitely not as the 3rd one behind KP + Horford. It's obvious. For a 7' 2" guy he's super soft and somehow can't outrebound or outhustle other guys either. He also can't generate his own offense so if others' can't facilitate it for him, he truly is just a "walking dead" guy out there.
2. Some of Mazzulla's issues continue to show unfortunately. Team goes on a big run and he doesn't even try to stop it. "Let them keep playing". Joe, do you want to actually win the game?? And when other teams build pressure on us or have certain advantages, Joe struggles to make adjustments. I wouldn't discount a team like Philly adding Nick Nurse. Nurse and Spo are the kind of coaches that can make a small difference in a playoff series and probably outdo Mazzulla as well.
It’s weird for this to be a game to single out Kornet. I don’t necessarily disagree with any of your points, but the entire team was garbage defensively, especially the bigs. I’m not sure why you’d single him out. He actually had one of his better games all season and lead the team in rebounding, which again is more of an indictment on the rest of the team
If Kornet was let go, I doubt any team would sign him for anything more than mop-up duty, kind of like Tacko Fall on this team in the past. Idk what Stevens sees in him. They were better off keeping Mo Wagner, and I'm not even saying that just because of yesterday. He's turned into a solid role player for them and had more potential to begin with.
When Porzingis or Horford are out, Kornet is the next guy up and that's where we get screwed. Even in his "better games" he got abused defensively and finished with a -2. Horford was also awful no doubt, but that's typically an outlier for him. Kornet had 6 rebounds, probably should have had more if he was actually physical and hustled more. Kornet started off well with 8 quick points but then had only 4 in the final 15 mins he played.
Brad better add a 3rd big by this deadline. We can survive for now, but if Kornet has to function as our 3rd big beyond March we are very screwed. But yeah, I'm just not a fan of his, sorry
