Last year the bullpen was the strength of the team, and the one area that didn't need to be improved on heading into 2014. This year, the same cast of characters single-handedly cost the team the playoffs, apparently.
There's a lesson to be learned here: worry about a rotation that's 5-deep and lineup/bench that's 12-deep, and support those guys with quality talent in AAA. The bullpen will sort itself out. Or it won't. But it's such a crapshoot that investing in it while having other holes in the roster is a terrible idea.
The 2014 Jays were replacement-level at 2B and C. They've given over 1600 plate appearances to Navaro, Kawasaki, Pillar, Thole, Diaz, Mastroianni, Reimold, Johnson, Goins, and Sierra. That's more than 26% of playing time wasted on replacement-level scrubs that the FO should have known were replacement-level. The quickest way to improve is to cut the fat. But they won't.
