He was done the day he left Michigan. And yes, I realize he set the American record in the mile after that. So let me explain: He left Michigan because he expected to run 3:49 his freshman year, and when the results didn't come immediately, he decided to go back to what he knew. And thus set in motion a cycle of prioritizing short-term gains in favor of any long-term plan. He seemed to live and die with every workout and race. He never seemed to peak at the right time. His tactics could leave you scratching your head. There was never anyone who sketched out a long term plan, reined in his training, and got him to relax, see the big picture, and gain confidence in what he was doing every day. And even despite al of that, he still ran 3:46. What a goddamn talent. But oh how things might have turned out if he had only stayed at Michigan.That's my arm-chair analysis.
