"I just need to re-evaluate at the end of this coming year what's going on, where I am, how I'm feeling," Collins said. "I've always said a lot of it will be dictated by how I'm feeling. This was a tough year."
In particular, Collins cited the demands of the big league travel schedule as a prominent factor in his thinking. He was hospitalized due to an illness in June, and he speaks often about the rigors of traveling as much as he does.
Collins has been involved in professional baseball continuously since the Pirates drafted him in the 19th round in 1971.
However, Collins has also reached new heights of career success in New York, making his first World Series trip in 2015. He is 481-491 overall with the Mets, which included overseeing their rebuild from '12-14. Following the '15 season, Collins accepted a two-year contract extension that expires after next season.
