Oh my God, sheff, you are a f***ing retard. I'm guessing you weren't even alive in 1986. Bill Buckner had awful knees. They were worn down and just plain s*****. He had an impossibly difficult time. Johnny Mac left him in the game because he was a big part of the team and he wanted his core guys on the field when they won it all. So, arthritic knees and all, Buckner was in the game, he got a tough play that he bad knees did not allow him to properly make and the ball got through his legs. I'm also guessing that you had no idea that it was Game 6 in which that happened and the game was already tied anyway.
You are a stupid f*** and I honestly cannot see you lasting more than 5 more minutes here with your blatant ignorance. Go f*** off now.
