To be honest I'm more worried about Beckett than Dice-K. Not necessarily in terms of injury, although Beckett has had more injuries so far, but rather, in terms of effectiveness. Beckett seems to be overrated in terms of his effectiveness, as he hasn't had many "amazing years". I know Dice-K hasn't been in the league that long, but unless Beckett goes back to his 07 numbers, then Dice-K looks like he'd have a better year.
Dice-K obviously has his baggage, as I'm yet to be able to watch a Dice-K start without changing the channel due to high blood pressure, but I'd count on Dice-K before I'm able to count on Beckett, that's all I'm trying to say. I'm prepared for people to try and jump on me about that...
