Eight players from the Cubs officially became free agents on Wednesday, entering an exceptionally unpredictable market this offseason.In all, 147 MLB players were declared free agents after the conclusion of the World Series, with the possibility of more joining their ranks when contract options are declined. On the Cubs, Daniel Descalso, Jon Lester and Anthony Rizzo all have 2021 team options.“The only thing I can acknowledge is that we're in a period of great uncertainty,” Cubs president of baseball operations Theo Epstein said in his end-of-season press conference. “That's industry-wide and also as far as our organization goes.“If you think about it, we're at a point where we know what our losses were this year; we don't know what our revenues are going to be next year. We don't know how many fans we're going to be able to have and at what different points in the season. Because of that and the fact that 29 other teams are in a similar situation, we don't know what the free agent marketplace is going to look like, what the trade marketplace is going to look like.”Since Epstein’s last public comments, the landscape has already shifted. Major League Baseball opened the NL Championship Series and the World Series to a limited number of fans at Globe Life Field. So, it seems likely that at least some teams will be cleared to put fans in their stands next season. But how many will have that financial advantage and how it will affect their offseason strategies remains to be seen.The free agent market will continue to shift in the coming months as teams gain more clarity on factors like playoff format, roster size and rule changes. In the meantime, here are the eight Cubs that enter that uncertain free agent market:
