I think SOR is still a key metric, but I don't know for sure. You're right on SOS and L10, although I think L10 may still matter behind closed doors. If I were them I'd want more than a qualitative answer, though. It leaves you open to so much criticism, as opposed to being able to throw out a quantitative reason. But that may also just be how my brain works, I tend to be more numbers driven.
Right, I think Red may be going to a slower offense to waste more time earlier than he perhaps should under normal circumstances but especially in the NET era.
If you think about it, if there are 10 minutes left and you use 30 seconds every possession, and your opponent uses 10 seconds, each pair of possessions takes up 40 seconds. You'll each get 15 possessions. If you average 0.5 points per possession and they average 1.5, both extreme, they can only close a 15-point gap.
Assuming Judah playing iso ball in the last 6-8 seconds averages around 0.8 points per possession at worst, you can take the air out of the ball pretty early. But it's going to kill your NET.
What good is winning games if you don't get in the tournament? I'm not saying you should be treating it like a shooting gallery either. But run the offense, keep taking open shots as they present themselves, and try to keep the margin up.
