The refs are never the sole reason for a loss, but they certainly hurt Baltimore's chances in a 33-28 defeat in Kansas City.
The Ravens were on the wrong end of several calls that had huge impacts on the game.
It started with a roughing the passer call for a horse-collar on Ravens linebacker Matthew Judon when he chased Chiefs quarterback Patrick Mahomes outside the pocket on an early third down deep in Ravens territory.
Mahomes threw an off-balance pass that was going incomplete as Judon took him to the turf. Judon did grab the back of Mahomes' jersey, but that was hardly what brought him down. The penalty extended the drive that ended with a touchdown instead of a field-goal attempt.
"When you give that offense that many opportunities, eventually they're going to capitalize, and they did," safety Earl Thomas III said.
In the second quarter, a holding call on Willie Snead IV wiped out a 45-yard run by Gus Edwards that would have put the Ravens in the red zone. Snead was blocking on the edge and instant replay showed a good block.
The Ravens were trailing, 14-6, at the time. Instead of having a chance to tie the game, they punted and the Chiefs pulled away with a touchdown on the next drive.
"It kind of threw me off," Snead said. "I felt like I had my hands inside, was moving my feet and I felt like I was in front of him. Gus made a great cut and got loose. I feel bad that it was called. I've got to see the play. I don't know how bad it looked on TV."
"Yeah, [the referee] explained it and I disagreed with it," Head Coach John Harbaugh said. "I let him know what I thought about it. He told me what he thought. We'll see what the graders think."
In the third quarter, Brandon Carr intercepted Chiefs quarterback Patrick Mahomes in the red zone, but safety Tony Jefferson was flagged for defensive pass interference. The Chiefs scored a touchdown three plays later to take a 30-13 lead.
"I'm not going to sit here and argue with the ref. He made the call. I just disagree," Jefferson said. "It is what it is. We just have to be better, play better, cover better."
On that same drive, there were offsetting penalties on both teams. The Chiefs had two penalties and the Ravens were flagged for one (defensive holding), which was attributed to cornerback Tavon Young, who is on injured reserve.
Rookie wide receiver Miles Boykin was also flagged for offensive pass interference on a series in the fourth quarter when the pass went behind the line of scrimmage, which means it was a lateral and Boykin was a run blocker.
"When we get turnovers taken away from us, that definitely affects the game tremendously, in my eyes," Thomas said. "Flags can be a big part of the game."
