Nate Robertson has always been a favorite of mine. He's been a great Tiger in the community and was an underrated pitcher in his early years. Unfortunately, he can no longer retire Major League hitters at a suitable rate.
In this day and age of the seven-man bullpen and endangered pitchers, a black hole cannot be hidden in the bullpen. This is evidenced by the fact that Robertson has been brought into games twice this week with narrow leads. While it hasn't come back to bite the Tigers, it could in the near future.
The $13.84 million dollars that Robertson has left on his contract are on the plate. The Tigers should be hungry enough to simply eat it already. It's not going to go anywhere else.
