Different messages for different audiences with different purposes.
What is your message when, for the first time, you're walking into the player's room of a 1-11 team? It's going to be some variant of "I want everyone who will not buy in to insanely hard work to get out, because we're going to work insanely hard."
You can be country white boy Jesus with it. Or you can be super-sincere born-a-teacher with it (the new Grolesh guy has this vibe at USF). You can be matter-of-fact businessman about it. You can be angry screaming guy about it. Or you can be Deion about it. But at the end of the day, coaches all say basically the same thing because that's just the truth of how things have to go.
Bo Davis on the ISU bus, "GET IN THE MUTHAFUCKA'! THIS IS REAL!"
Anyone who genuinely believes that Deion Sanders was actually telling the entire CU roster to leave is an idiot. A straight-up waterhead. Not only is that not what he said, but it doesn't even make sense. This guy has been deep in organized football for 40+ years.
If I'm walking into that player's room, 1-11 team, knowing a lot of guys on the team didn't even bother to show up to see the new coach, I'm probably not going to be saying, "Gosh, fellas, I'm just so honored to be here and I can't wait to continue the winning tradition! Thanks for the opportunity and I know I have a lot to learn from you guys!"
