Yep, but that was their last loss of the regular season. They won the next 8 games in a row, including as
@drewskie said blowing out the Jets 45-3. That team was as hot as it gets entering the playoffs. After that Browns lost the scores were:
39-26 @ Steelers (the eventual AFC champs)
31-28 vs Colts
45-24 @ Lions
45-3 vs Jets
36-7 @ Bears (went to the NFC championship game)
31-27 vs Packers (although without Aaron Rodgers)
34-3 @ Bills
38-7 vs Dolphins
That's an average score of 37.4 - 15.6. That stretch was 2007esque. Brady set the record for most passes without INT, was the unanimous MVP. And then it all went apart in the Divisional against the Jets.
