Coming into the Sunday with only three yards to go before he held the record for the most passing yards in NFL history, there was little suspense Peyton Manning would make history at Sports Authority Field against the Chiefs.

Indeed, he passed Brett Favre's 71,838 yards in the first quarter. But it was all downhill from there.

The Denver QB's numbers at halftime were absolutely putrid, going 4-of-15 for 30 yards and three interceptions. Though no injury has been reported, his former coach in Indianapolis, Tony Dungy, is ready to diagnose one anyway.

Peyton added a fourth interception in the second half and finished with a passer rating of 0.0. That's when the Broncos finally pulled the trigger and put in Brock Osweiler. The fourth-year quarterback didn't fare much better, throwing another interception, as the Chiefs won 29-13.

It was first time Peyton has completed less than half of his passes in a game since 2007. And it's a fair argument to be had whether he's causing more harm than good for the Broncos right now.

But is Osweiler really the answer? Or can Denver regroup and figure out a way to hide Manning's flaws? This is coach Gary Kubiak's riddle to answer.
