The Auburn sophomore, who was making his first start of the season, filled in at right guard for Byron Isom, who couldn't go after taking a blow to the head in practice earlier in the week.
"I felt like we played good the first half," he said. "We didn't come out with the same enthusiasm as we did the first half. We didn't finish."
Berry said the Mountaineers were successful with their second half strategy. "The first half we were killing them with the outside zone so in the second half they brought more guys up to the line of scrimmage. They just started crowding the box."
Berry, who started three times last season, said he thought he played well in the first half as the Tigers built a 17-3 lead early in the second quarter and led 17-10 at intermission. "The second half I made a couple of mistakes," he said. "Other than that, I played okay."
Auburn's previous three losses were all close games that one play could have changed the outcome. West Virginia outscored Auburn 24-0 in the second half and scored the final 31 points of the game to overcome AU's two touchdown lead.
Asked how his he and his teammates feel after a third straight loss, Berry said, "We are just ready to get back to practice. We are ready to get back to work."
The Tigers return to action a week from Saturday with a road trip to Ole Miss.
