it's a bit of david robertson syndrome. He's been good, but not as electric as we thought.
Happens with bullpen though. You have to pay a lot just to maintain the last years success, it's just a sinkhole of a position. To get near the success of Colome last year (no blown saves) we had to pay a lot more, because had we paid colome he'd have been terrible. There's no easy answer there for sure.
