Interesting question, I don't know if people are waiting for the other shoe to drop but there's a lot to be worried about.
The Sox have a terrible offense right now and they're winning mostly on pitching which rarely if ever lasts in the A.L. East.
Things that worry me.
1. The offense.
2. Ortiz and Manny have WEAK hr/rbi totals and have been decidedly unclutch this year.
3. Lugo (SUCKS), Drew and Coco have been offensive busts for half the season, all of them hitting under .235 for much of the season. Of course Lugo is hitting .188 now.
4. The defense is not particularly good this year with Lugo at shortstop and Lowell having a sub-par year defensively. Lugo is a weak shortstop.
5. Good pitching demands good/great defense and we don't have it.
6. History says that Youks and Lowell will slow way down offensively in the second half. That would kill us.
7. Schilling is looking old and frail.
8. Wakefield, if his ball isn't dancing all he's doing is throwing batting practice pitches. Hell, his fastball is only around 72 MPH, that's slower than bp pitches.
There are times when it seems amazing that we have such a big lead with that offense and parts of the defense. If not for Beckett, Dice-K, Tavarez and the two STUDS in the bullpen we wouldn't be very good.
