ORCHARD PARK, N.Y. -- Observed and heard in the locker room after the Miami Dolphins' 29-10 loss to the Buffalo Bills:

Frustration: The overall theme in the locker room Sunday evening was frustration. Nearly every player who addressed the media felt he could have played better to help avoid a blowout loss. The Dolphins were beaten on offense, defense and special teams. “We made some mistakes that we usually don’t make,” Dolphins Pro Bowl cornerback Brent Grimes said. Miami is 1-4 against the Bills in its past five meetings.

Tannehill owns up: Miami starting quarterback Ryan Tannehill owned up to his shaky performance against the Bills. Although the loss wasn’t on one player, Tannehill didn’t do his part and finished with 246 passing yards, one touchdown and one interception. “We didn’t win so it’s not good enough,” Tannehill said. “No part of our offensive performance was good enough.”

No Moreno: One key player who was missing in the locker room Sunday was Dolphins running back Knowshon Moreno. He injured his elbow in the first quarter and never returned.
