I will give you the age thing, although I do think the Yankees are at a point where 4-5 of their best hitters could face serious decline, in which case your offense would be unspectacular. Beckett's not going to have a 4.50 era, iIF YOU KNEW ANYTTHING ABOUT BASEBALL AT ALL you would know that the adjustments Beckett made last year were exactly what he needed to do to be a dominat ace. He slowed his delivery and made the effort to throw 10% less FB which was an absolutely huge difference.
Also about Manny, I am going to go look at past film because I think you are pulling the one inch back thing out of your ass, SO WHAT? He is leading the leauge in RBI's and has missed three homeruns to dead center field by inches. I have watched Manny for 8 years almost everygame, his swing looks much more clean this season than it was during his Abysmal 07 season.
