I don't think Wright can do enough damage for a team to "really regret" replacing a Gearrin with him.
Moves at the periphery of the 25 man roster just don't have that much impact.
The Mariners are "really going to regret" letting a 33 year old journeyman relief pitcher go?
I don't see where Wright is much of an upgrade but this is end of the roster type stuff. No one ever really regrets losing a Gearrin.
