I would say all of it.
Athleticism. Dusan, AP, Connor are all very slow, lack lateral quickness, mobility. Beagle is not strong enough to play against larger center. Our 2 guards are very athletic but short and can be passed over very easily when we double.
Coaching: I don't honestly know what we are doing. It seems like our coaches know we lack athleticism and most of our players can't guard 1 on 1. So, we are using double teams, more help side defense, but that is leaving the 3 ball wide open and we see a lot of flying Dutchman.
Pride/Competitive Edge: Man, I don't see it. We got dunked on repeatedly and just continued to let it happen. We let Auburn treat us like little boys. This has always been a big complaint of mine with Mooney based teams. He coaches a soft brand of basketball (we don't go after offensive rebound, our offense is based on "fluidity", back door cuts, he is happy for us to "compete". So, unless a kid is hardwired to be really competitive, they aren't getting the edge from the coaching staff and the way they approach the game. I really hate this about Mooney ball, basketball is a competitive contact sport and too often he wants to play sissy ball. A team might not be the most talented but I always want a team to be physically tough and give 110% effort. We don't play that way as a function of our system.
Last year, we had guys who had that strong competitive fire and they collectively were able to bring that to the court. This year, we have Delonnie, and he isn't getting any help from the way Mooney approaches the game to breathe that into the other guys.
