Colts-Dolphins halftime observations

Posted by ESPN.com's Tim Graham

MIAMI -- The Miami Dolphins and Indianapolis Colts enter halftime tied at 13 on "Monday Night Football."

Some observations from the Land Shark Stadium press box through two quarters:

The Wildcat gets frisky: The Dolphins ran the Wildcat four times in the first quarter for 33 yards, including Ronnie Brown's 14-yard touchdown to tie the score on their opening drive. The offense needed a spark after last week's performance in the Georgia Dome, and the Wildcat seemed to provide it.

Brown gains one fewer yard on Miami's first possession than he had all last week: Brown looked like a superstar, running for 42 yards on the opening drive. He went into the half with 83 yards. He eclipsed the 100-yard barrier three times last year, topping out at 125 in Week 5.

Dolphins tackle Jake Long has done well against pass-rush specialist Dwight Freeney: Long had a rough opener against the Atlanta Falcons, giving up two sacks, half a sack less than the total he gave in his Pro Bowl rookie season. Freeney recorded a sack in the second quarter, but it was due to the Colts' coverage on a play that forced Chad Pennington to scramble.

Peyton Manning seems to be completing passes at will: Manning has completed 7 of 14 passes for 159 yards and a touchdown. His percentage isn't that great, but he's hitting them when they count. He connected with Dallas Clark for a 20-yard pickup to put the Colts in field goal range with two ticks left in the second quarter. Adam Vinatieri kicked a 48-yard field goal to tie the score.

The Dolphins must figure out how to contain Clark: He scored an 80-yard touchdown on the game's opening play, and three of his four receptions have been for first downs.

Dan Carpenter has made two difficult kicks for Miami: He nailed 45- and 44-yard kicks in the second quarter, both of them off the Florida Marlins' infield dirt.
