Agree completely. Being a fan is no longer enough on blog sites. You gotta be a GM and/or President of Baseball Operations. It's not about winning and losing as much as it is making a deal--and not a DD deal, but a smart deal that lowers the total salary of the Sox.
So, even though the Sox have the best winning percentage and the most wins in MLB, Talksox is replete with discussions about preparing for the worst, dumping good players deemed no long affordable, etc.
So far this year the Sox hitting is the best in MLB, the rotation is almost decent, and the bullpen is bringing up the rear. A "save" these days has a bad odor, but this year Barnes has saved the Sox ass repeatedly. JD Martinez's OPS is 1.127 with 10 dingers and 31 rbis. His War is 2.0. Barnes's WAR is .9, tied for highest on the Sox pitching staff.
So to me it's so simple. Plan on keeping Barnes because he's doing a great job and actually helping to win games. I will admit an age bias on this point. I frankly am less interested in the 2022 season or, heaven forbid, the ones after.
About Barnes. I think the key to his success is relying on just two pitches, a terrific knuckle curve and a decent fast (95 mph) fastball. He doesn't need any other pitches because those two together keep hitters off balance and he can focus on hitting his spots. Uehara did exactly the same thing with the slowest fastball in the history of organized baseball, a devilish splitter, the control of a knife thrower you only see in movies, and the guts of a high-wire artist. The only difference is that Uehara actually had a personality.
