I agree that it's more important to follow the timetable that is best for the player. How good or bad the team is should not be a factor.
Hess, Scott and others are brought up from AAA before they are ready and then seem to start a shuttle. I'm not sure that bringing them up early hurt their chances to succeed in the majors, but it certainly didn't help and it's not worth taking a chance on someone like Akin. I'd like to see him win 10-15 games and maybe be the best pitcher in the league this year, which truly means he has nothing left to prove. Then it will be up to him whether he makes it next year or just becomes a AAAA pitcher like some of others we have.
