What if Josh Beckett is good next season?In all the rush to imagine a Dodgers rotation with Masahiro Tanaka or David Price, we haven't paused much to reflect on whether the Dodgers really need to exert that kind of energy and money. Granted, Beckett was hard to watch last season as he labored through those eight starts before shutting down his season.But let's not forget he was pitching with a painful condition in his upper rib cage called thoracic outlet syndrome (TOS).
