You know, jacko, for all the crap I give you, I respect you a lot, and I know you know more about medicine and injuries than I do, but I'm not sure where you get your data from.
1) You once claimed Sale's velocity fell off a cliff, and the fangraphs graphs I provided showed a much less drop than you claimed.
2) You ignored Sale's success after his short-lived return, despite the drop in velocity. (His highest K rates of his career were 2017, 2018 and 2019, including a 13.3 K/9 in 2019.
3) Now, you mention that his "control suffered." When?
True, his 2019 BB/9 (2.3) rate was higher than his previous few seasons, but his career BB/9 is 2.1, so that seems pretty slight when you factor in he was recovering while pitching.
BTW, his last 3 games of 2019 saw him K 29 in 18.1 IP and walk only 2.
His last 2 games, he had 25 Ks in 14.2 IP with 2 BB and 7 hits (1.84 ERA)
Look, you may end up being right. You may even probably end up being right, but Sale was great as soon as 1.5 years ago.
He's not old. Many pitchers have comeback from what he has suffered. You may end up eating your words.
I'm not saying he will return to norm, but if he can come back to just 75% of his best, he could still be a great starter and possibly better than anyone on the Yanks, except Cole, assuming they don't "comeback" as well as he does.
I realize many Yankee starters have "lesser injuries," but so do Eovaldi and Richards. (ERod is the biggest unknown.)
