As you may have read, the Jays were in the hunt for pitcher Matt Clement until the last minute. (Or maybe the fourth-last minute. Or maybe 11:07 or something.) The question: how much would Clement have helped the team had he been signed?
My claim is that signing Clement, or any middle-rank starting pitcher, is a bad idea for the Jays. Why? Because almost all established pitchers acquired by the Jays get worse in a Toronto uniform. And this has nothing to do with J.P. Ricciardi, Rogers Communications, the current Jays coaching staff, or anything like that, as this has been happening for a generation now.
The following table lists all the significant pitchers acquired by the Blue Jays since 1983. “ERA-B” (B is for “before”, natch) is the pitcher's ERA the year before the Jays got him; if he was acquired in mid-season, it's the pitcher's ERA at the time of the trade. “ERA-A” (A is for... you guessed it) is the pitcher's ERA when the Jays acquired him.
