There were probably 50-60 people there? I'm not that great at estimating crowd sizes, but I think it's fair to say a decent crowd showed up for the event.
Buzz was cordial and seemed more relaxed in a practice environment than he normally does when speaking to the media. He communicated messages to his players just fine.
Ron didn't shake my hand as he was on the other side of the gym. I didn't stay for the dinner afterwards so it's possible he went around to everyone then.
The players seem to listen to him just fine. They seem to welcome coaching.
Tough to comment on the "teaching" question as they mostly were going over drills they've done before. I thought he did a good job explaining to screeners how to read different defenses.
Also, based on the drills we were running, I'd be looking for us to utilize a pack-line defense.
