I don't think you are taking into account how important pitching is going to be during this stretch in your schedule. Not only do all the teams you play have a winning record, but they are hitting the heck out of the ball right now.
Sure, Moose and the Unit will get you some wins during that month, but what happens if they have an off game (like they have each done more than once this year)?
Wang's been serviceable, but very hittable too. He's managed to wiggle out of several innings where it looked like crooked numbers were about to go up.
That's 3 starters. May started today (1st start) and served up 3 shots of "Jack" in a 7 ER, 4 1/3 IP performance. Sturtze is your other spot starter, and he got creamed in his first start against the O's.
Wright and Pavano are close to coming back, but they have been extremely hittable this year, so that wouldn't fill me with confidence.
I'm concerned. Concerned about how we play, how you play, and how the O's and Jay's play. I'm confident too. We have a good squad, and if we can find consistant relief out of someone (Timlin, Schilling, whoever), I think we can go on a good run. But I'm also willing to admit that some things about this team don't make me comfortable.
I think you, and several other Yankee fans, are approaching this next month with blinders on when you say "Don't worry, we will win most of the games against those good teams". Confidence in your team is admirable, but "blind faith" without acknowleding the difficulty ahead seems less like confidence and more like denial.
