While I don't necessarily object that he's a buy-low, I don't think it's right to characterize this problem as him being a "slow starter" ever year. Last year, he put up horrible stats for my team in the first 4 weeks or so, but after 30 IP he had struck out 40 or so for an absurd K rate. I knew he was getting really unlucky with hit rate, so I stuck with him and it paid off.
There was no indication of a health problem last year, whereas this year there is a very clear medical issue that is affecting him. The hip is hugely important for all pitchers, but even more so for Bedard (his motion relies on a very dramatic rotation of the torso, since he's one of those guys who twists until the hitter is basically looking at their backs before unleashing).
