The bullpen was perfectly average last year, Gregg aside. It's not like it has to be better from last year for the team to do well. Yes, it could easily be worse since we're talking relievers here, but analysis of last year's team that acts like the bullpen was a major problem isn't exactly realistic. The problem was much more along the lines of the underwhelming offense leaving too many close games for the bullpen to hold while the bats went dead.
