Pineda is moving from Petco AL to NYY, Burnett is a mess, we still don't really know what Nova is, he wasn't projected to be as good as he was last year, what do you get from Kuroda? Does Garcia repeat his performance? Joba is post-surgical, so who knows what happens with him.
A-Rod and Jeter are a year older, Teixeira has been trending down for four consecutive years, you traded away Montero, which Martin shows up for the whole year? The world-beater or the pedestrian and does Granderson repeat his performance?
Those are all valid questions that are easy to see without the pink glasses on.
As for the rest of your post, there is the same type of "if only" that you so condemn on Red Sox fans. Be consistent.
