Eovaldi should have been an improvement over what Pomeranz gave us. I don't think it's a fair assessment to say that Dombrowski did nothing to improve the team. No, he probably didn't make as many improvements as other teams did, but when you're the WS Champs coming off a 108 win season, really, how much improvement can be done?
I get the whole argument about not improving the bullpen, not that I agree with it, but I get it. But he did improve our starting rotation, which IMO, was the main area in need of improvement. Our offense was and is fine as is.
