Over his last six games, Brown has 64 receptions for 868 yards and six touchdowns, and Pittsburgh has scored at least 30 points in each game. At this rate, he will earn strong consideration in the voting for offensive player of the year.

With 116 catches through 14 games, Brown is 28 receptions from breaking the single-season N.F.L. record, set by Marvin Harrison in 2002. Brown is also nearing the single-season record for receiving yards, set by Calvin Johnson in 2012. Brown has 1,586 yards and needs 379 to break the mark. Given Brown’s dominant play and the poor pass defenses of Pittsburgh’s next two opponents, Baltimore and Cleveland, neither mark is out of reach.

Of course, had Roethlisberger not missed time this year with an injury, Brown would have a much higher chance of breaking those records. In three games started by Michael Vick this season, Brown totaled just 11 catches for 111 yards and no touchdowns; Brown can match those numbers in about three quarters with Roethlisberger.

Brown has been one of the best wide receivers in the N.F.L. for each of the last three years. He had 1,499 receiving yards in 2013 and 1,698 yards last year, and he will almost certainly set a career high this season. He and Jerry Rice are the only players with at least 1,499 receiving yards in three consecutive seasons, and he and Wes Welker are the only players with at least 110 receptions in three straight years.

Given the number of great receivers in the game today, including some players who are flashier than Brown, it is easy to overlook his consistent run of greatness. But observers should not: He is currently producing at one of the best rates in N.F.L. history.
