The first round of the NFL playoffs featured four excellent games. All four were decided by one possession. Two went to overtime. Three road teams, including both No. 6 seeds, came away with victories.
One surprising element was that the four games averaged just 36½ total points. In a league that has skewed toward offense in recent years, that's low. Expect the divisional round, which will bring rising star quarterbacks Lamar Jackson and Patrick Mahomes into the mix, to feature more points.
Let's take a look at the key questions for the four divisional-round games:
Minnesota Vikings at San Francisco 49ers
Can Kirk Cousins ride the momentum of Sunday's win into another strong performance?
Cousins was at a crossroads entering Sunday's game at the New Orleans Saints. He brought in a 6-30 record against winning teams, and a loss might have destroyed the Vikings' confidence that he could ever lead a championship team.
A major cloud lifted when Cousins hit tight end Kyle Rudolph for the winning touchdown in overtime. The locker room was electric afterward. The Vikings will be playing with house money going into a matchup with top-seeded San Francisco and Coach Kyle Shanahan, who was Cousins' offensive coordinator with the Washington Redskins and might have made a run at him in free agency had the 49ers not traded for Jimmy Garoppolo.
Cousins has some major weapons around him in Rudolph, running back Dalvin Cook and wide receivers Adam Thielen and Stefon Diggs. The 49ers shouldn't take them lightly.
What is the 49ers' key to victory?
They need a big game from their front four. Earlier this season, that would have seemed like a given, but their talented defensive line has been decimated by injuries. Edge rusher Dee Ford has been fighting a hamstring injury for a month. Nose tackle D.J. Jones is on injured reserve.
Getting a bye in the first round was huge. It also gave the 49ers a chance to sign Earl Mitchell, a 311-pounder who came out of retirement. Controlling Cook in the ground game and getting pressure on Cousins will be critical.

Tennessee Titans at Baltimore Ravens
Can the Titans repeat the ground-game success they had in New England?
Running back Derrick Henry rushed for 182 yards and a touchdown on 34 carries in the win over the Patriots, a powerhouse performance that made it easier for quarterback Ryan Tannehill to get his first victory in Foxborough, Massachusetts. He only had to throw 15 passes, completing eight for 72 yards and a modest 61.0 passer rating.
A repeat performance is unlikely. The Ravens were the fifth-best run-stopping team in football, allowing just 93.4 rushing yards per game, and defensive coordinator Don "Wink" Martindale has deployed some great schemes this season. Tannehill probably will need to do more for Tennessee to pull another upset.
Can the Titans find a way to slow down Lamar Jackson?
Nobody has all season, so it's hard to imagine Coach Mike Vrabel and his Titans can. The problem Jackson presents is twofold: He might be the best running quarterback in the NFL, but he is also efficient when throwing from the pocket.
The Ravens averaged 33.2 points and 407.6 yards. The Titans might need to take a few more chances and try to force turnovers to keep pace.

Houston Texans at Kansas City Chiefs
Which Texans team will show up?
It's impossible to know. Houston simply hasn't been consistent, and that was on display in Saturday's win over the Buffalo Bills. The Texans were terrible in the first half, leading to a 13-0 deficit, but quarterback Deshaun Watson overcame being sacked seven times to lead his team all the way back in a 22-19 overtime victory.
One of Kansas City's most important tasks will be keeping Watson in the pocket. He is one of the best quarterbacks in football when he escapes.
Who will win the quarterback matchup?
Watson vs. Mahomes may not match the Peyton Manning-vs.-Tom Brady matchups of the past two decades, but their rivalry has that type of potential. The visiting Texans won the teams' Oct. 13 meeting, 31-24; Mahomes threw for three scores, and Watson paired 280 passing yards with 42 rushing.
With Philip Rivers and Brady facing uncertain futures, the AFC is being handed to the young passers: Watson, Mahomes and Jackson.

Seattle Seahawks at Green Bay Packers
Can Russell Wilson continue to win close road games?
Don't count him out. Sunday's 17-9 victory over the Philadelphia Eagles was just another example of how he can manage a game and make enough big plays to win. The Seahawks were down their top three running backs, and top offensive linemen Mike Iupati and Duane Brown missed the game, too.
Wilson was magical Sunday, throwing for 325 yards and rushing for 45. Seattle's running backs only rushed for 19 yards, yet he was still able to make big play-action passes down the field. Rookie wide receiver DK Metcalf caught seven passes for 160 yards and a touchdown.
If Wilson can avoid the Packers' impressive pass rush, he is more than capable of winning at Lambeau Field.
How much pressure is on Packers quarterback Aaron Rodgers?
A lot. Even though Rodgers led Green Bay to 13 wins, critics have been questioning him all season. Despite one of the best Packers running attacks in years, the offense ranked 18th at 345.5 yards per game. Part of the problem is he doesn't have many pass-catching threats beyond Davante Adams.
Rodgers reached 4,000 passing yards, but his completion rate of 62.0 percent was his lowest since 2015. There's a lot of pressure on Rodgers not to blow this shot to make the Super Bowl by losing a home game.
