Make 4 million per year over 3 years with a very high possibility of being fired after that. Or 2.5-3m per year over the next 15 years if not slightly more than that. Barring an implosion of the program or ridiculous honor code violations from the team and possibly himself. He could hold this job probably for as long as he is willing to keep coaching. There is a lot of happiness that comes from being so secure and in a job that you love.
