I guess my issue with this critique is that it ignores the fact that improving at the deadline was always going to be more difficult for the Brewers than for other contenders, not because of organizational philosophy or budget issues but because of simple logistics.
One of the reasons for the Brewers’ success is that they don’t have a ton of weak spots (or at least won’t once their outfield is healthy).
They could use one more reliever, which they got, but didn’t need to remake their bullpen. They didn’t need another starter. If you think Vaughn’s chase and walk rate improvements are sustainable, he could easily provide Naylor-type production even if he cools off from his absurd early pace. Between Vaughn’s start and Durbin’s rise, you are getting decent or better production from 8 spots,
Shortstop has obviously been an issue. However no shortstops were dealt, and the only one definitely available (IKF) has probably been worse than Ortiz the past couple of months.
That left the bench, and they did improve there. I might have preferred that they pick up one more bat, but overall the Brewers were never likely to upgrade as much as the Padres, Mets or Phillies did because the avenues to do so were simply greater for those teams.
