Tim Tebow, the Florida Gators (later New York Jets) quarterback tended to get excited when on the Gators sideline and in the locker room. Even when he's low key, he can give a hot blooded speech!
"I'm sorry. I'm extremely sorry. We were hoping for an undefeated season. That was my goal, something Florida's never done here. But I promise you one thing: a lot of good will come out of this. You have never seen any player in the entire country play as hard as I will play the rest of this season and you'll never see someone push the rest of the team as hard as I will push everybody the rest of this season, and you'll never see a team play harder than we will the rest of this season. God Bless."
