BALTIMORE -- Buffalo Bills coach Sean McDermott said he will "look at everything" from his team's 47-3 loss Sunday to the Baltimore Ravens before deciding who will start at quarterback next Sunday against the Los Angeles Chargers.
"It's too early to go one way or the other," he said. "I'm gonna look at everything and be objective and make sure we put ourselves in a position to win games."
Peterman, whom Bills coach Sean McDermott named Week 1 starter last week, completed 5-of-18 passes for 24 yards, 2 interceptions and a 0.0 passer rating. He was also sacked three times. Peterman and the offense failed to gain a first down until the first play of the second half, a 12-yard run by LeSean McCoy.
"Overall, I thought we could have been better at a number of positions," McDermott said after the game. "I've gotta look at the tape, to be honest with you, to get a better feel for exactly making sure we were in the right spots for him as well before I give you a better readout on that."
It was the first time Buffalo failed to gain a first down in the first half of any game since at least 2001, while Buffalo's 33 total offensive yards in the first half were the team's fewest in any game since they gained 11 against the Miami Dolphins in a December 2003 game.
Buffalo's 44-point loss was the second-most lopsided defeat in franchise history after a 56-10 loss to the New England Patriots in 2007.
"Obviously it wasn't a good showing," Peterman said. "You got to do a lot of things better, starting with me. A lot of plays I wish I could've had back, obviously. But that's football, and it's about going back tomorrow, tonight and this whole week is about moving on but learning. Taking a hard look at yourself, learning from these mistakes but moving on and trying to go win another game."
Allen entered the game with 11 minutes, 22 seconds remaining in the third quarter and the Bills trailing 40-0. He finished 6-of-15 for 74 yards and was sacked three times.
"It's a situation where obviously it's not the most desirable situation," Allen said. "I was going in, just trying to make plays, just trying to help this offense move the ball."
Added McDermott on Allen: "I thought he made some pretty decisive throws in there, into some tight windows. He used his feet at times, as well. I thought he had pretty good command of the huddle and the offense at the line of scrimmage. Other than that, we'll go back and look at the film and evaluate it."
The Bills' 153 total offensive yards were the 11th fewest in franchise history, while the team's 10 first downs were Buffalo's fewest since 1979.
Peterman's first interception came in the second quarter, when he overthrew Kelvin Benjamin over the middle of the field. His second interception came in the third quarter to Ravens cornerback Brandon Carr, who returned it 32 yards to the Bills' 1-yard line.
Sunday marked Peterman's third career start. In his starting debut last season, he was intercepted five times in the first half of a 54-24 loss to the Los Angeles Chargers before being benched at halftime. He started two weeks later in place of an injured Tyrod Taylor against the Indianapolis Colts.
The Bills selected Allen with the No. 7 pick in April's draft, the highest draft pick Buffalo has ever used on a quarterback.
