Defense wins championships and that's widely known to any coach, player and fan. Certainly, last year's dolphins defense was not primed in any way to compete for a championship and was a disaster. This year is a whole new defensive team with an infusion of rookie’s vets and leftovers from previous seasons. Now look I am not rushing to say the dolphins have a championship defense, after 6 weeks they look pretty good.
Hanging around playoff teams, New England, Buffalo and Seattle in one score games, compared to last year is a massive improvement. A complete destruction of Jacksonville, the 49ers and the Jets, The Dolphins Defense look to build upon their streak against the Los Angeles Rams.
