Here we go again. For just the fourth time since the 1970 merger, two teams will meet in the AFC Championship Game in back-to-back seasons. It also happened from 1974-76, when the Raiders and Steelers met three straight times, in 1978 and 1979 (Steelers-Oilers) and in 1986 and 1987 (Broncos-Browns.)
The Patriots, who finished at 12-4 and as the No. 2 seed, are making their ninth appearance in the AFC title game. That ranks third in AFC history behind the Steelers (15) and the Raiders (11).
Here some other numbers to crunch on about the Ravens' opponent on Sunday:
0: The number of touchdown passes Tom Brady threw against the Ravens in the AFC Championship Game last season. That snapped a streak of 18 straight postseason games with a touchdown pass by Brady, two shy of Brett Favre's career record.
2: Number of Jones brothers who will be playing in this game. Patriots defensive end Chandler Jones is the younger brother of Ravens defensive lineman Arthur Jones.
7: The number of AFC Championship games the Patriots have won, out of the eight they've played in. They are 4-0 in the AFC title game at home.
10: The number of consecutive seasons the Patriots have won at least 10 games. That is the second-longest such streak in league history, bettered only by the 49ers' run from 1983-98.
11: The age when Patriots punter Zoltan Mesko moved from his native Romania to the United States after his father won a green card in a lottery. The family settled in Ohio and he ultimately starred at the University of Michigan
17: The number of playoff wins as a starting quarterback by Tom Brady, the most in NFL history. Last week he broke the record previously set by Joe Montana.
18: The number of games in which Wes Welker has caught at least 10 passes. That is an NFL record, passing the mark of 17 held by Jerry Rice and Andre Johnson.
34.8: The Patriots' scoring average this season, the best in the league. The Patriots topped 50 points twice and 40 points six times, including in the AFC Divisional Round last weekend when they beat Houston, 41-28.
74.1: Tom Brady's quarterback rating in seven career games against the Ravens. That is his lowest rating against any team in the league.
50,000: The number of dollars Patriots coach Bill Belichick was fined for making contact with an official as they left the field after the Ravens' last-second, 31-30 win over the Patriots in September.
