He was an LSU pitcher in the late 80's, before any CWS titles. 1989 Golden Spikes winner and until Skenes recently, the only #1 pick LSU ever had. I think he lasted less than 10 years in the majors and was "okay."
I was young, but my impression of his time at LSU was that he was far and away the best pitcher, and Bertman kinda treated him like "You're our Friday ace, get on out there and gimme a complete game. Come to think of it, try to keep your count down anyway because I need you to close out Sunday too, can't be too careful. Also, go ahead and pitch this midweek game, we need to win all those we can, you'll have two full days rest before Friday, don't act like you're tired."
I don't know what the actual story is, but the general sentiment amongst fans is that Skip blew out his arm with over-use. At least one of his teams got to Omaha, which probably helped them when the 90's started.
I generally enjoy listening to him on ESPN. He kinda has a lot of the same accent as Orgeron, without the gravely voice. Which is weird, because I think McDonald is from Denham Springs.
