If they right pitcher was available, I'd consider shelling out big bucks this offseason, but I don't think he exists. This year's class is Rodon (if he opts out), deGrom, Wainright, Eovaldi, Bassitt, Kershaw and Verlander (if he doesn't take the $25M player option). I like Bassitt, but he's not going to command a huge salary. If he does, it's just not worth it. I don't see Wainright, Kershaw or Verlander leaving their current teams. DeGrom is a great pitcher, but has a large injury risk attached to him (his results look pretty good since coming back, but his launch angle, barrel % and exit velocity are all up, which may not be an indicator of future success in the AL East - he may be good, but underperform the enormous contract he wants). Most likely the Mets don't let him leave either. I like Eovaldi, but year to year, some of those AAV's aren't worth it at what he was previously paid.
A lot of people like Whitlock in the pen because he was a lockdown guy in 2021. I think he has the right pitch mix to be a successful starter. I think Houck is more suited for the pen as a two pitch guy. Sure, Whitlock's ERA will go up by a run, but that's to be expected. It doesn't mean he's "worse" as a starter. I'd rather get 170 innings out of him in the rotation. However, if the Sox do start the season with Whitlock in the pen, they just need to leave him there. The constant shuffling is just dumb.
