It’s that he sold himself as something better than he was. He collected tens of millions of dollars he didn’t really deserve or earn.
Earning tens of millions that they dont deserve is par for the course with professional athletes, i.e. Barry Zito in San Francisco.
He's a former MVP, 5 time All Star, led the AL in walks multiple times, OBP multiple times and has won the Silver Slugger Award twice. He didn't deserve the money he was paid? Yes, he's got the steroid scandal surrounding him, and he's had a couple serious injuries in his tenure with the Yankees, but all in all, I think he's performed quite well and earned his money, to boot. The only drawback that I see with him is that he can't hit the opposite way...
