Well, there's a couple things that'll give you pause.
Brian Urlacher missed his 5th practice in a row, while Brett Jackson struck out 5 times in a row (going back to his first game).
Lovie Smith and Dale Sveum will try to calm the masses, but that stuff is out there.
Certainly injury is way more worrisome than a habit of striking out.
I've got huge expectations for the Bears this year, and none for the Cubs.
Anyway, these are the things that are lodged in my brain right now.
Sorry to add to your concern.
