Lately, Mets manager Terry Collins has acted so mellow, so indifferent to the losing and injuries, that it seems to me that he's accepted he will not be back next season. And, interstingly, he also seems OK with it.
According to multiple reports, Collins has told people he's unsure if he'll return to managing after this season. There have not been any reports indicating Collins and the Mets have discussed a contract extension.
Basically, it's time. His job here is done.
Remember, when he was first hired, the Mets were looking for someone to help change the clubhouse culture.
