We all know injuries happen, and can make or break a season. This is why teams look for depth, or at least one of the reasons. So my question at this time is, where are the 49ers most exposed? If ____ got injured, we'ld be up a creek. I think clearly we are wearing very thin at DB, and I wish we could add a little more depth there. Where do you think we run the most risk for a season devistating injury? If Gore goes down, do we throw in the towel? Willis? Davis?
