One way to fix childish coach behavior is the assigning system. Houston TASO has NFL quality guys, have them assign. Sounds ridiculous, but the crew wants games so they don't even flag the doofus. Let each coach scratch one crew, then let assigners handle the rest. "Yeah, but this is how it has always been done!"Well, coaches are in education, so that should tell you all you need to know about that system, and I am a teacher.
While I am ranting, get rid of the get back coach. Here is how to do it. Start taking time-outs away. I worked a chain recently, and it is easier to get through GCS (Grand Central Station) at rush hour than to move up and down a sideline in the 2nd half.Take away a second half time-out and watch how far back the players get.For most coaches its time-outs, God, then family.
