Williams burst through a hole for 14 yards on the Dolphins' first offensive play, and the Dolphins were in business at the San Diego 17-yard line. But after getting a second-and-goal at the 1, they had to settle for a 20-yard Olindo Mare field goal.
The Chargers answered back with a field goal of their own, which capped a 57-yard drive that was greatly aided by a stupid personal foul penalty on Sam Madison, who shoved Tomlinson for no apparent reason after a play.
But that was about all that went wrong for the Dolphins in the first half.
After the San Diego field goal, the Dolphins used a little bit of trickery to give themselves great field position as Travis Minor handed off to James McKnight on the return and McKnight brought it back to the 40-yard line.
A holding penalty on Chris Chambers negated a touchdown run by Ricky Williams, but it didn't matter because on the very next play Lucas hit McKnight in the back of the end zone for a 20-yard touchdown and a 20-3 lead.
Early in the second quarter, the Dolphins put together their longest drive of the season — in terms of number of plays — and the 14-play march paid off with Williams' 1-yard touchdown plunge on third-and-goal.
After the Chargers' Steve Christie missed a 42-yard field goal, the Dolphins marched another 48 yards to tack on Mare's 38-yard field goal just before halftime and make it 20-3 after two quarters.
It was more of the same in the second half, as the Dolphins tacked on 10 more points, first on Williams' 12-yard touchdown run and then on Mare's 23-yard field goal that followed a 77-yard pass play from Lucas to McKnight.
