I think when you look for blame in every situation it can obscure the truth. I mean look at a guy like Caleb TBar. He was a set up for a post playing career as a pitching coach for a small college when the Twins called. Well into his 30's. It is a tough racket at a certain point perseverance is the most important thing. Roster rules dictate how much patience a team can have, then it just comes down to picking the players you hope will perform. Sometimes there is no one to blame.
