They might be a dime a dozen but when a bullpen blows up, it can take down a team. That's what happened to Brewers in 2012. Yeah Fielder was gone, but Ramirez had a terrific year, Bruan was at the top of his game, Gomez was emerging and Lucroy and Maldonado combined were terrific and Hart was very productive after move to 1B. But Axford, Rodriguez, Veras, and Parra were terrible. That team should have been a playoff team. They won 83 but bullpen was historically bad. With an average pen, they win 90+ even after dealing Grienke. The pen was combined a -7.1 WAR, by far the worst in the NL. That 2012 year ticks ya right off. We don't get many windows to have teams like that and our pen completely ruined it.
