Really it boils down to the pussification of the modern athlete. Everyone talks about the flopping NBA players but top of my list is the MLB starters! “Ooo I throw too hard and catch pitch as much!”
I don't disagree with that at all. It's hysterical watching pitchers limping to the finish line at 90 pitches when Ron Darling talks about throwing 190 pitches in a game at Yale and 130+ in MLB games.
But have to play the hand you have...and it's pretty clear what we have. Peterson has never been a workhorse. Holmes might be next year, but he needed to be at 130-140 innings this year. Megill can't be part of 5-man rotation (even with the extra days off at the start of the season) or he will be injured by May. His consistency there is almost comical. Senga absolutely needs to be part of a true 6-man rotation. Our bullpen was completely destroyed by July from overuse.
I understand not wanting to mess with a stud like McLean -- and I think they handled his development perfectly -- but why not throw Tidwell, Blackburn, and Sproat more often? If they get rocked, at least it completely saves the A bullpen arms and gives your starters extra rest?
