All Sox fans would have loved to get something for him, but this isn't OOTP. He is a guy who had major injuries and hadn't had an actually good season in five seasons before last year. He came off of TJS in 2019, so both that and 2020 were washouts where he showed nothing. 2018, he had a FIP near 5, and his strikeout rate and stuff fell off pretty hard, probably because he was nursing an injury which turned into his TJS a year later. 2017 he was hurt again with only 12 starts and didn't even make 70 innings.
Taking all of that into account, the entire world had a crack at him in the 2020-21 offseason, and literally no one was willing to offer him anymore than what Vince Velazquez got as a free agent. If he had trade value, he would have been signed for A LOT more than $3 million and an invite to spring training. Pitchers with trade value get a LOT more, both in terms of years and dollars.
So as you attack everyone for saying the obvious, when do you think they should have traded him and what value do you think he had pre-2021? I sure don't see it, but let's actually hear you logic instead of your hurt feelings.
