One of my relatives works for the NFL he stated early on, before all the BS, that the Krapper wouldn't be drafted. A quarterback needs to lead the team, to have the linemen willing to fight to protect him. No one liked the Krapper.
The difference between genius and stupidity is that genius has its limits. Albert Einstein
He wasn't that good of a QB. If he had the talent he thinks he has then he would be signed. No talent, a big mouth and not being a team player means he doesn't play. He could shut up, practice more and take care of the team but that isn't how he rolls.
You get out of life what you are willing to accept. If you ain't happy, do something about it!
