How sure are we he did steroids?

[Gonzo]

Juan Gonzalez is my favorite player. I lived outside Dallas from 1989 to 1993 when i was from age 3-7. He was my idol. I used to have all his baseball cards. I'm 21 now and had the privelage of watching all the Rangers postseason appearances (here in NY unfortunately) even though it was hard to watch.

With all the steroid stuff it seems pretty clear to me he did them. Did this contribute to his injuries? If he didn't have so many injuries he would have been an all-time great. Now it seems like he was just a guy who did steroids and put up some big numbers because of it.

This really pisses me off. The one player who I really looked up to as a kid was cheating the whole time. How do you guys feel about it?
