SATURDAY
AFC
No. 6 Indianapolis (10-6) at No. 3 Houston (11-5)
When: 3:35 p.m. (Ch. 5/ESPN)
The matchup: The Comeback Bowl features teams that went 4-12 last year. Indy's Andrew Luck, who missed last season, is second in touchdown passes (39). Houston's Deshaun Watson, who missed nine games last year, is the first NFL player to pass for 4,000 yards and 25 TDs while rushing for 500 yards and five TDs.
Key stat: The Colts gave up a league-low 18 sacks.
Colts win Super Bowl if … Luck gets hot and the 10th-ranked scoring defense (21.5) plays four games like it did in shutting out the Cowboys last month.
Texans win Super Bowl if … Watson stays efficient and explosive and J.J. Watt keeps channeling Reggie White, the only other player with four seasons of at least 15 sacks.
NFC
No. 5 Seattle (10-6) at No. 4 Dallas (10-6)
