Chances the 49ers are done?

[OldSchool]

Harbaugh has been winning because of a dominant run game and top 3 defense. Justin Smith's age is going to catch up to him sooner or later, Whitner will be gone, Rogers will be gone, Ray Mac is already slowing down, Gore is slowing down, Boldin will likely be gone as well, etc. Kaepernick is clearly not a QB who can be relied on to carry the team and win and if the 49ers are dumb enough to sink some major money into him, then they are done, lol.
