I think worried is too strong a word, at least for me .... I would say I'm concerned, but not a lot. Let's remember, this amazing turnaround we had was precipitated by the loss of Perk and Rage, and I think the team handled it pretty well, to say the lest. This team has presevered through "loss due to injury" all year, and come out shining.
I still remember how freaked out everyone was when KG went out, and we played great! We've taken up the slack with grit and determination all season, and I have little doubt that we won't do so now. I also think it may add to the Lakers being a little over-confident on Sunday, and that's a mind-set I'd love to see them in!
