This is correct in my opinion, and the disadvantages of such a strategy are at least as significant as the supposed rewards.
Basically, it is the Dick Jauron line of thinking. It would be an erroneous approach when the Bills on paper are at least on par talent wise with Miami if not superior (taking into account offense, defense, and special teams). The only way this plan could be justified is if Buffalo was significantly overmatched in every area versus the opponent.
