First time I've seen the video. I don't know Coach Osborn, have never meet him (I know coaches at both schools in other sports, all good people) But let me be devil's advocate....I'm gonna try and be the one person to give him some benefit of the doubt from watching the video...
Game ends, some CG kids rush the floor. In my opinion this isn't a really egregious "court storming" as the group more or less just runs out to celebrate with the CG players. Quite a bit of space between benches and this crowd. Not near as many people as I assumed based on the way I'd heard it described.
Carmel players start to head over to shake hands with a few CG players on other side of scorer's table. But most CG players are in the celebration near center court. Carmel coach points for team to go back other way and around to leave.
So now Carmel Coach is directing his team to go back around the crowd on their way out. They have to cross the scorer's table agin to do this and go out other end. During this time Coach has his back toward the CG celebration and there is space between him and Carmel players who are doing as they are told and heading out.
At about this same time, it appears the CG players are being directed to go "shake hands" with the Carmel team and a line of CG players now starts to move between the exiting Carmel players and the Carmel coach. Players all look to be exhibiting good sportsmanship here. Looks like some CG coaches/officials are also trying to stay between this handshake line and the crowd...good for them.
Carmel Coach is now kind of on his own, on the CG side of the handshake line, and starts to head towards the end of it to meet up with his team...
Now from that point on, I can't tell from that grainy video what happens.
But as a coach who has been around a lot of handshake lines...I don't see him "purposefully" storming through the crowd...at least initially. I think he didn't realize CG players were gonna walk through when/where they did for a handshake and he tried to cut around it as best he could.
Did he do something inappropriate at the end? I sure can't tell from the video, so I won't say he did or he didn't. But I think my interpretation is at least a little different than some others....
Flame away if you want....just my 2 cents
