No, not a bridge year. There's a difference between a bridge year and letting kids develop in place.
This is the issue I had with dealing Masterson when they did. He had all the potential he's showing now, when he was here, ground ball pitcher with strikeout stuff, poised with all the talent to dominate in the rotation, but no one seemed to want to let him go through his growing pains in the rotation and everyone kept wanting to squeeze him into the bullpen instead as a result.
Heck I'm as guilty as anyone else when it came to Buchholz, but that's mostly because my first impression of the kid was as a guy who couldn't buy a third out to save his immortal soul and when he wasn't missing bats, the ball was getting launched. Masterson had neither problem.
Masterson could wind up as one of the top pitchers in the league for a long time -- he's got all the stuff he ever needed to do it -- and they sacrificed that for 1 1/2 years of a catcher who should have been DHing because "he's a reliever!" Just because that's what he first started succeeding at. Still frustrates me.
