"Don't throw it to the other team," Philbin said.
Bush finished with only four carries for 21 yards.
Jake Locker, back after missing five games with a dislocated non-throwing shoulder, went only 9 of 21 for 122 yards but threw for touchdowns covering 9 yards to Kendall Wright and 26 yards to Jared Cook.
Locker also ran for three first downs, which vexed defensive end Cameron Wake.
"You've got to stay in your rushing lanes and contain — basic simple fundamental football," Wake said. "There's nothing dramatic. He didn't go out there and grow wings and fly around. He ran the ball, and we didn't contain him."
The tone was established early, when Jason McCourty recovered a fumble by Bush at the Dolphins' 28, and Tennessee converted the turnover into a touchdown.
"Our defense put us in some good situations all day," Locker said. "It wasn't pretty at times, but we found ways to move the chains."
The Titans even transformed pratfalls into big plays. Locker tripped as he dropped back to pass and fell 10 yards behind the line, then rose and scrambled to transform the broken play into a 20-yard gain. Four snaps later, Locker converted a fourth down with another scramble, and Johnson then scored on a 17-yard run for a 14-0 lead.
Ayers made his first career interception to set up a field goal for a 24-3 halftime lead. There was no letup in the second half by the Titans, who opened the third period with an eight-minute, 85-yard touchdown drive.
"There's no explanation, no excuse," Wake said.
NOTES: Tennessee's Rob Bironas set a franchise record for most consecutive extra points without a miss, breaking Al Del Greco's mark. Bironas has made 232 in a row. ... The loss was the worst at home for the Dolphins since they were beaten in their third season 48-3 by Kansas City. ... The Titans trimmed their defensive scoring average from 34.2 points per game to 31.1. They're no longer on an NFL-record pace. ... Tennessee played volleyball in the first quarter when Kenny Britt and Wright dropped the same pass.
