Yeah, the writing was on the wall before the deadline. After the franchise best 32-18 start they went 25-27 heading into the deadline. Here are the splits from those two runs of games...
04/07-05/30 (32-18)
PIT: 81 ERA- (4th) | 83 FIP- (2nd) | 8.2 rWAR (4th) | 8.6 fWAR (1st)
OFF: 228 RS (7th) | 103 wRC+ (10th) | 7.0 WAR (7th)
About what what we expected coming into the season, a dominant pitching staff and an above average offense leading to one of the better teams in baseball.
06/01-07/31 (25-27)
PIT: 107 ERA- (18th) | 106 FIP- (21st) | 3.1 rWAR (20th) | 3.1 fWAR (23rd)
OFF: 239 R (12th) | 111 wRC+ (7th) | 9.9 WAR (6th)
Offense mostly held serve adding 8 points of wRC+ and almost 3 WAR, though run scoring fell off a little relative to the rest of the league. Pitching in the tank. Hader missing time and giving up runs in bunches instead of putting up all zeroes the main culprit (+1.5 rWAR first 50, -1.0 rWAR next 52). During this stretch the pitching staff essentially consisted of four guys, Burnes (1.6 rWAR), Williams (1.6 rWAR), Woddruff (1.5 rWAR) and Box (0.7 rWAR). Our fifth best pitcher during this stretch was Jandel Gustave (0.3 rWAR), that pretty much says it all.
Throw in the rest of the season to this point (28-30 record post deadline) and the offense at 720 RS (10th) | 103 wRC+ (11th) | 23.5 WAR (8th) has mostly met or exceeded expectations relative to last year's 738 RS (11th) | 98 wRC+ (19th) | 18.8 WAR (15th).
Pitching on the other hand went from 83 ERA- (3rd) | 87 FIP- (3rd) | 26.4 rWAR (3rd) | 23.4 fWAR (3rd) in 2021 down to 95 ERA- (7th) | 98 FIP- (14th) | 15.0 rWAR (14th) | 14.5 fWAR (14th). The league ranking in ERA- is fine, but still a 12 point drop from last year's mark and when you throw in the unearned runs the overall run prevention unit is over 11 wins behind 2021.
Sure, a better deadline could have bought a couple two tree extra wins, but ultimately Hader has put up -0.9 rWAR for SD and Bush/Rogers have combined to put up -0.9 rWAR for us, so at least we got Gasser/Ruiz to replace Kelly/Peters.
Ultimately the Brewers missed the playoffs due to a number of factors, but it's hard for me to chalk up the majority of the blame to anything other than the foibles of pitching.
We returned 11 of our top 13 pitchers from that 2021 staff that was 3rd best in MLB across the board, losing only Hunter Strickland and Brett Anderson. Those eleven returning pitchers - Woodruff, Burnes, Freddy, Houser, Lauer, Suter, Boxberger, Hader, Williams, Ashby and Cousins - combined to throw 1,064 innings totaling 30.0 rWAR in 2021. Those same 11 pitchers have thrown 1,025 innings this year tallying only 16.7 rWAR.
I just don't see the math on how all the other moves or non-moves can add up to a difference greater than that.
