I remember when he came up and made his MLB debut. Those were really exciting times to be a Brewer fan as they were right on the cusp of finally being competitive with these young players.
I wonder if his decline was being overworked, bad conditioning, or just a combination of the two. I don't recall him ever really having over-powering stuff, but he threw his pitches for strikes. Later in his Brewers' career, it seemed like he nibbled more and more and I recall several times where he just couldn't get guys out before it was a 3-2 count with several foul balls.
