A false start penalty on left tackle Eric Fisher followed. Jason Avant caught a 4-yard pass to put the ball at the 3, and a defensive pass interference penalty on Logan Ryan put the Chiefs back at the 1.
"There were probably a lot of opportunities that we left out on the field," safety Eric Berry said.
Four plays later, unable to find an open receiver, Brady sprinted — sort of — for the corner of the end zone. The Chiefs managed to keep him out, but only for one more play. On the next snap, Brady leaned forward and reached into the end zone to make it 14-3.
"You've got to be able to take advantage of that when it comes," Smith said. "You don't know when you're going to get opportunities like that with that kind of field position, right on the fringe of field-goal range. I mean, if you get any yards there, you've probably got points and we weren't able to do anything."
After trading punts twice, the Patriots started on their 2 when punt returner Danny Amendola was flagged for a helmet-first hit to coverage man Jamell Fleming.

"It's a fine line of getting into the best play and just keep going at the line of scrimmage," Smith said. "It would've been nice to get a score before the two-minute warning. It would've helped tremendously with three timeouts. It probably hurt us there."
"It gives us a great example of where we need to be," Reid said.
"We went hurry-up offense,Wholesale Football Jerseys China," Reid said. "You normally do that when you're down by two scores. Time was of the essence. We got down to the 1-yard line and ended up going backward."
"I tried to play,Cheap Shoes Free Shipping, and I did," he said. "And then it came to a point where the pain kind of took over and it was time for me to come out of the game."
"I never felt we were out of it," Reid said. "That's not how I felt in this game. That's why I look forward to the next opportunity that we have like this."
Trailing the New England Patriots by two touchdowns, Alex Smith and the offense burned more than 5 minutes off the clock to score, a mismanaged try that left the Chiefs with a 27-20 loss on Saturday that ended their 11-game winning streak.
Then came the two-minute warning.

FOXBOROUGH, Mass. (AP) — The Kansas City Chiefs' comeback attempt came up short — and took way too long.
"I appreciate him for going out there and trying to go," Smith said of Maclin. "No one expected it. It was pretty gutty."

There was also the 19-yard punt return by Frankie Hammond Jr. that gave the Chiefs the ball at the Patriots 36. They lost a yard and were forced to punt on the three-and-out.
"We wanted to get a play off right there. We had 20 seconds," Reid said. "It was 2:20 on the clock. We wanted to make sure that we got our best personnel in for that play and we didn't get that done."
