I reckon he has no interest in landing Guerin at this point. And probably for good reason--I imagine the asking price is still ridiculous.
This could just be a tactic in the eleventh hour, but it's just as likely that it isn't. He did say, after all, that he's perfectly willing to go into the postseason without any major additions.
I'm hoping it has something to do with Bert, but...oh well, we'll see.
