As the Mets slog through the second half of a losing season, it's logical to anticipate changes on the horizon.

With Amed Rosario at shortstop and prospect Dominic Smith not too far behind, the Mets are about to get younger in an effort to retool for bigger things next season. That may also include trades of veterans like Jay Bruce and Curtis Granderson.

But the biggest change the Mets may make over the next two months could generate an entirely different reaction from fans: Ousting manager Terry Collins.

ESPN's Buster Olney speculated on Collins' future in a column, suggesting that the Mets be up front with Collins about their plans for him when this season ends. If the franchise ready to walk away from its all-time wins leader, Collins should have the ability to decide on his own exit date.

That his situation remains unresolved is just one indication that there doesn't seem to be a clamoring within the Mets organization to retain Collins, and it may well be that -- after seven years of managing the Mets -- he's ready to move on to something else. Nobody has said anything out loud, one way or the other.

At 68 years old, Collins -- a baseball lifer -- might prefer to get to the finish line of the season. Or, if the Mets don't intend to bring back Collins, maybe they could offer him the opportunity to go home for the final weeks of the season. With this much service with the Mets, he should be given the right to choose, and to answer questions directly and honestly about what his future will be beyond the last game of this season.

As Olney noted, there's been very little spoken on either side. At the end of last season, Collins appeared to be leaning toward leaving the game after the 2017 season.

Collins owns a 530-551 record as manager of the Mets, including a magical run to the World Series in 2015.
