"The one [throw] at the end of the half was ill-advised, to put it kindly," Billick said.
"I thought I saw Todd in the end zone," said Boller, one week removed from leading a game-winning drive against Houston. "I just tried to make a play. But I made the play worse."
Taylor had a hand in one of the Ravens' four turnovers, fumbling at the Ravens' 42 in the third quarter. The Broncos used that to extend their lead to 12-3, as Plummer hit fullback Kyle Johnson for a 7-yard touchdown.
On the Ravens' next series, Boller locked onto Heap and was picked off by Champ Bailey at the Denver 6-yard line.
But Boller, who received solid protection behind a makeshift line, wasn't finished. After the Broncos fumbled at midfield in the fourth quarter, Boller lost the ball on the next play, fumbling while trying to tuck the ball away.
"It slipped out of my hand," Boller said. "I can't catch a break, I guess. It slipped out of my hand. I can't give you any other reason."
There were few explanations about the Ravens' ongoing problem in the red zone. The Ravens, who were in Denver territory on seven of 10 drives, scored three points on three trips inside the 10-yard line against the NFL's third-worst red-zone defense.
"We're cursed in the red zone," Heap said. "That's where you win in this league, when you get the ball in there and score points."
In their worst season since their first (1996), the Ravens have clinched their second losing season in Billick's seven seasons and can no longer stomach any more moral victories.
"Honestly, there's nothing you can take out of this game," Mason said. "Yeah, we played hard but what it boils down to is wins and losses. That's what makes a franchise and that's what breaks one."
