How can you come up with this prediction?

I read and listened through many predictions for 2008 season because I want to know how they make these predictions even though I am not interested in making prediction at all . I sometimes can't understand some people's logic of their predictions.

Here is the example. If you predict that Yankees are not going to make the playoff because of our pitching staff in spite of our strong offense, how can you predict that Tigers are going to win it all because of their strong offense despite their suspect pitching staff? The same logic apply to Red Sox's pitching staff as well. If you suspect Yankees' pitching staff, how can you not to suspect Red Sox's pitching staff?

How about those picks for Angels or Mariners over Yankees when Angels got two ACEs out and Mariners' questionable pitching staff? Come on, guys. I know Felix Hernandez and Erik Bedard are great "ACEs", but When Felix is going to put everything together while Bedard step in and out of DL all the time. On top of that, who are their No.3 to No.5 pitcher?

Unbelievable!
