He would have been much happier if his New England Patriots didn't have to overcome another first-half deficit to do it.
"I wish we could start fast and put the foot on the gas pedal the whole way," Brady said.
"It's not the way we want to play," he said. "Hopefully, I can find a way to coach better than I've done, find a way to get ahead."
"We're playing hard, we're not always playing good," Kubiak said. "We had a lot of opportunities to make plays ourselves, just didn't make enough."
New England overcame a 24-point first-half deficit last week to beat the Broncos 34-31 in overtime. The Patriots (9-3) trailed by 10 at halftime in this one, and the lead changed five times in a wild second half. New England tied it with a 53-yard field goal and took a 34-31 lead with another one from 53 with about three minutes left.
"Whatever we're doing is not good enough, and we can't keep getting behind because you have to play too well in the second half to overcome," Brady said.
The victory ended a three-game road skid for the Patriots, who have won their last eight December games and 16 of their last 17 in the month. The victory assured them their 13th straight winning record.
"It's a big plus," Belichick said. "We have to find a way to win on the road. Fortunately, this week we did it. The last three we were in similar situations to this and didn't do it."
