Thanks for the lecture grandma, but you can take the white knight fluffery elsewhere where it's wanted. The poster in question has a history of troll level nonsense and I've yet to see a single post that adds anything of value to any discussion. This site has no tolerance for dumbass opinions so I'm not sure why you are so quick to jump to the defence of this particular poster unless you've also been a regular receiver of ass whippings because of your own poorly thought out opinions.
Berrios is a good number 2 starter and one of baseball's most consistent starters year in and year out. This poor opinion is so off base that it almost immediately labels anything else that is said as not worth even responding to. The guy potentially has another level of performance he can reach but even if he doesn't he's still a very valuable member of the rotation.
Blaming Ryu for individually causing the team to miss the playoffs is equally as asinine. The last I checked baseball was a team sport, and one individual's performance doesn't make or break a season. Despite Ryu's second half struggles he still provided 2.5 WAR for the season, and in 2020 on a per inning basis he was nearly as valuable for the Jays as he was for the Dodgers in his walk year. I can go ahead and blame Joe Panik or TJ Zeuch for the team missing the playoffs since each guy was a sub replacement "contributor", but that's not exactly a reasonable take is it?
Ryu and Kikuchi certainly each struggled in the second half, but given how short 2020 was and the sudden crack down on any sort of grip enhancing substances I think guys can receive a bit of a pass. it's likely that a combination of fatigue and lack of ability to grip the baseball to the degree to which they were previously used to each became issues. Kikuchi had a very nice 5 month run in 2020 and the first half of 2021 where he performed like a number 3 starter, and if he can put everything together he has potential for that type of performance again given how good his stuff is. If he flounders a little and is a bit inconsistent (like basically every other fifth starter out there) he's only being paid 5th starter money, so this isn't a super risky deal that should immediately be panned as a bad signing before he's even taken the mound for the Jays in a regular season game.
