Matthew Stafford says "I've got to be better" after NFL-record 33rd career pick six

"We've got to be more efficient with some of the stuff we're doing throwing the football. Obviously, I've got to be better, and I will be," Stafford said.

Stafford threw two fourth-quarter interceptions, both to Denver 's Talanoa Hufanga , one of which was returned for a touchdown. That one gave Stafford his 33rd career pick-six, breaking a tie with Brett Favre and giving Stafford the most pick-sixes in NFL history. Stafford was as frustrated after the game at his inability to tackle Hufanga as the interception.

"Obviously don't want to have a pick-six," Stafford said. "Hufanga makes a good play, I couldn't get him on the ground and that's points to them there."
