Knowing "what it takes", and being able to actually pull it off, are two different things. The Captain of the Titanic knew what it "took" to avoid icebergs, and over the last 96 years, we have seen how well that worked out.
That having been said, I think he meant it more of a compliment than a "dig" at the Pats. Having played the Pats this year, I think he realizes that you have to play 100%, all game long on your end to have a chance to derail them. (And possibly hope the Pats make a few mistakes along the way).
