Moore led two straight touchdown drives in Miami's 20-14 preseason victory over the Tampa Bay Buccaneers on Saturday night.
"We got into a little bit of a rhythm. Guys were in the right spots, making big plays," said Moore, who completed 13 of 19 passes for 158 yards and a touchdown.
"I was just trying to execute plays and maybe questions were answered, I don't know. I was just being me."
The Dolphins took advantage of a mistake by Bucs rookie Mike Evans that turned the game around in the second quarter.
Evans, the Bucs' first-round pick from Texas A&M, caught a short pass from Mike Glennon and after breaking a tackle, sprinted down the sideline toward a 42-yard touchdown which could have given the Bucs a 14-3 lead.
After a review of the original touchdown call, however, it was ruled that Miami cornerback Brent Grimes had punched the ball out of Evans' hands just before Evans crossed the goal line. The fumble went through the end zone, giving the Dolphins (1-1) the ball.
"If it's a game that matters, then (Evans) scores because he's learned from it," Bucs quarterback Josh McCown said. "But yeah, he was pretty ticked off at himself."
Bucs coach Lovie Smith was also inclined to give the rookie some slack.
"I know Mike fumbled the ball, but it was a great play to get it down to there," Smith said. "He'll learn from his mistakes. My rookies are doing too many great things for me to harp on that."
Moore, competing with newcomer Brady Quinn for the No. 2 quarterback spot, drove the Dolphins 71 yards to a touchdown in the final 1:41 of the first half. He completed 6 of 8 passes, including a 9-yard touchdown pass to Rishard Matthews that gave Miami a 10-7 lead over the Bucs (0-2) with 8 seconds left in the half.
"(Moore) played well. I thought he threw the ball well," Dolphins coach Joe Philbin said. "We'll watch the tape. I thought he had a good game."
Rookie running back Damien Williams ran 1 yard for the touchdown that gave Miami a 17-7 lead with 8:58 left in the third quarter. John Potter added a 51-yard field goal that made it 20-7 with 4:30 left in the third.
Dolphins starter Ryan Tannehill completed 9 of 14 passes for 110 yards, including a 16-yard completion to Matthews that set up the game's first score. Potter's 48-yard field goal put the Dolphins up 3-0 with 4:47 left in the first quarter.
Four plays later, McCown threw a 7-yard touchdown pass to Vincent Jackson to give the Bucs a 7-3 lead.
McCown completed 5 of 7 for 46 yards in three series.
Quinn, who signed with the Dolphins on Tuesday, played the final quarter and part of the third, completing all four of his passes for 22 yards.
"We felt very good about what he knew going into the game," Philbin said. "The type of game we were in, up by 13 points, it just didn't make a lot of sense to start chucking it a whole lot."
The Dolphins will play the Dallas Cowboys next Saturday night in their preseason home opener. The Bucs will travel to Buffalo to play the Bills next Saturday.
