Yasmani Grandal is going to get a bulk of the catching assignments in 2020. He is the guy who will start all of the big games behind the plate for Chicago but that doesn’t mean that he can play in every single game. Catchers need rest so if they were to trade McCann, one of the two backup options would need to step up.
The first option is young Zack Collins. He made his Major League debut for the White Sox in 2019. The White Sox have had high expectations for him since he came into the organization. He had three home runs, 12 RBIs and 16 hits in 86 at-bats during his 2019 rookie year. Obviously, the .186 batting average is worrisome but he is still learning the way in the league. If they believe he can play some good backup catcher and then maybe provide some help in the designated hitter and first base spots, he could be a good option for the Sox next year.
Another player who made his MLB debut in 2019 was Seby Zavala. He isn’t necessarily a long term answer to the backup position for the White Sox but he is definitely there right now. His debut wasn’t great but it was short-lived as he only appeared in five games. He only had one hit in twelve at-bats but that is way too small of a sample size. He might get his opportunity someday but the other options are more likely.
Obviously, trading McCann at this point is probably a long shot but these three reasons prove that there is at least a couple of reasons to consider it if a team calls with an offer that sweeps Rick Hahn off his feet. Having depth at the position is definitely nice as the team moves forward.
