Williams instantly upgrades the Dolphins. First, I don't think he is the best RB in the league, but I do think he is a big, bruising runner who can keep the chains moving with a good yard/carry average. This is exactly what the Dolphins needed to go with their suffocating defense, they are now a lot like the Ravens team that won the superbowl. Solid but unspectacular QB and receivers, improved Oline and good quality RB, defense that thrives on shutting the other team down when it counts. I don't know if the Fins will go to the big dance, but in my mind they are certainly a solid playoff contender with a chance. The Fins always get beat in the playoffs because their defense, which carried them through the season, was worn out at playoff time, and now they are a more balanced team.
