Interesting, but I believe the 5 man rotation has worked pretty well so far, the bullpen has been almost decent, and the Sox team ERA, 2.47, is still ranked #1.
To me the real problem, which the new CBO can't do much to fix in the short term is that, out of the $180M current payroll--11th biggest in MLB--$100M isn't playing for the Sox: Devers $29M; Story $23M; Giolito $18M; Pivetta $8M; Sale $17M; and Turner $7M.
You can almost tack on Yoshida's $18M because he ain't delivering on that salary.
So, let's see, now we're at roughly $60M worth of players who can actually play. Thank goodness the 5 original starters--Bello, Pivetta, Crawford, Whitlock, and Houck--are paid just $14M total.
Nevertheless, $60M, which does represent the value of the players actually able to play right now, is lower than the A's bottom of the barrel $63M.
So I go with moonslav's cautious approach. Watch and see. Maybe trade/dump the 1 year life cycle models like Jansen.
