KANSAS CITY -- Duke Johnson Jr. hasn't run the way he did Sunday since the midpoint of his final college season.

The Browns quarterback set a franchise record with his 111 rushing yards against the Chiefs, but it was one of the last things on his mind as he reflected on a loss that came with no shortage of missed opportunities.

Manziel breezed over the details of what caused his rushing total to nearly double in a single game, but lamented the throws he missed and the plays he didn't make in a game that ended with the Browns at Kansas City's 18-yard line and no more time left on the clock.

"It comes down to I don't think I was good enough during crunch time today," Manziel said after the 17-13 loss. "I thought I was extremely subpar and it cost us some points.

"The guys around me played good enough to win the game, and I didn't do enough for them."

After a rocky first half, Manziel and the Browns offense completely controlled the final 30 minutes, but ultimately came away with 10 points when they needed more.

Manziel spearheaded a Browns rushing attack that finished with a season-high 232 yards, the majority of which came in the second half. His chunk yard scrambles got the Browns started on an early third quarter touchdown drive that cut the Chiefs' lead to seven, and he moved the chains with his legs on Cleveland's other three possessions, all of which went at least to the Chiefs' 30-yard line.

Manziel, who has shown a strong knack to pass first even with open running lanes throughout his second NFL season, came into Sunday's game with 122 rushing yards over the course of nine games.

"We'll take yards and points however we can get them," Browns coach Mike Pettine said. "They were dropping into some deeper zones and doing a good job. We had to hit some throws underneath. I thought with the lead they started to soften their coverage some. Just like Alex Smith did to us, (Manziel) was able to do it to them."

Manziel, who finished 13-of-32 for 136 yards and a first-half interception, was able to identify at least one throw he wanted back on each of the final three possessions, which netted just three points.

On second-and-goal from the Chiefs' 8-yard line early in the fourth quarter, Manziel felt heavy pressure and tossed a pass as he fell to the turf to right tackle Mitchell Schwartz. The penalty moved Cleveland back to the 18-yard line, the Browns lost a down and ultimately had to settle for a short field goal to cap a drive that went 21 plays and took more than 12 minutes off the clock.

"I saw somebody flash and made a mistake," Manziel said. "I had plenty of time and was out of the pocket for the play and like I said, that's one that really sticks out where we gave up points. That was our touchdown drive that we needed right there and instead we got three and had to go back out and get another one. I'm pretty upset."

Manziel got the Browns right back into scoring position just a few minutes later thanks to a defensive stop that set the offense up with prime field position. Cleveland notched back-to-back first downs with a Manziel completion to Travis Benjamin and an 11-yard Duke Johnson Jr. run but hit a wall at the 32-yard line. Manziel threw three straight incomplete passes, the last of which went deep and away from any of his potential targets on fourth-and-8.

Manziel put the blame on himself for the wayward throw and was similarly hard on himself for the Browns coming up short on the final drive.

"I am definitely shouldering this one," Manziel said. "It sucks not to win, especially when coach and 10 other guys worked to get the win. I didn't do the right thing and that is the moral of the story."
