Here are my predictions. I think it is safe say to these individual will probably not be with the Cubs in 2020:
Pedro Strop - worst year yet in relief and closing. He is a free agent. With a 4.99 ERA in his contract year he is as good as gone.
Steve Cishek - 13 million contract price vs mediocre production. The Cubs will gladly let him enter free agency after his performance over the last two years.
Jon Lester - Continuously declining in performance. His record in 2019 does not show how horrible he truly was. Offense has bailed him out many times.
Brandon Morrow - Nobody cares why he will be gone and will soon forget he played for the Cubs.
Cole Hamels - He was to improve the overall pitching rotation. Cubs will part ways with him.
Nicholas Castellanos - the only player on this list the Cubs should fight for, but probably will not.
Ben Zobrist - Extremely reliable as player, but aged, becoming slow on the bases, and will not fit in future plans.
Ian Happ - 2019.... 'nuff said :(
