I think the only difference between both our arguments is that you want the best chance to win now. And yes, of course Dak would give us that over Lance, Coop or any washed up veteran we could acquire.
While my point is, that the ceiling for Dak is still somewhere below a Superbowl so it doesn't matter. That's why, after 8 years, I'd rather go with a rebuild now than try the same thing for another 5.
But each to his own, I know where you're coming from. And I know I won't change your mind. Or that of any other "pro Dak" person. And after months or arguing about it I have made my peace with that.
