When I envision Jose Valverde coming out of the bullpen for the Tigers, I don't necessarily see impending disaster.
I view it instead as a process of what somebody (honestly, I forget who) once referred to me as "weeding out the weeds."
The Tigers re-signed Valverde, whose meltdown in the playoffs last year is well-documented. They need a closer. They must determine whether he can fill the role.
