Paxton was a rehab guy and not going to pitch a full year at best.
Wacha had only pitched 124 innings the year prior after finishing up in the TB bullpen with a 1.1 fWAR. Hill was a mildly better acquisition coming off a career high 158 innings and 1.7 fWAR, but at 42 years old and didn't complete 6 innings in a start until mid May.
Those acquisitions don't get the blood flowing. Hill had 1.8 fWAR in 23 and Wacha had 1.5. That's less fWAR than the top four 2024 BOS starters: Houck, Crawford, Bello and Pivetta. I think we've overstated what those acquisitions really brought to the team.
