I think everyone agrees that the OL is the optimum starting point for our offseason rebuild, but it does seem like the options with which to do that in both FA and the draft are pretty slim. Ruling out a great trade or hitting lucky on a mid/late pick, we might have little choice but to look to internal development of the players we already have and focus our rebuilding efforts on areas with good options available - RB, CB, LB. It's one of the reasons I'm still highest on Kaepernick, he isn't entirely dependent upon a reliable pocket and makes defenses have to worry about him making plays on the run. Pair him with a drafted RB and Powell/Forte, and together with our young and improving WR corps I think we could have an offense that might not be winning Super Bowls, but will at least be capable of keeping opposing defenses on their toes despite a questionable OL.
