Marcellus Wiley favors the Bills over the Chiefs because he says Josh Allen is bigger, faster and has a better arm than Patrick Mahomes.

QUARTERBACKS

Josh Allen (Bills, fourth season)

5: Allen set a Bills franchise record for passing touchdowns in a playoff game with five last weekend against the Patriots. He also set a franchise record for completion percentage (84%) in a playoff game.

4: In the win over the Patriots, Allen passed for 308 yards and ran for 66. He became the first player in NFL history to have at least four playoff games with 250 yards passing and 50 yards rushing.

3: With the wild-card win, Allen improved to 3-2 in his career in the playoffs, becoming just the second quarterback in Bills history to win three playoff starts, along with Jim Kelly.

Patrick Mahomes (Chiefs, fifth season)

404: In Kansas City's 42-21 wild-card win over the Steelers, Mahomes set a Chiefs single-game playoff record with 404 passing yards. He joined Ben Roethlisberger as the second player in NFL history with at least 400 passing yards and five passing touchdowns in a playoff game.

5: Mahomes is just the second player since the 1970 AFL-NFL merger to throw five touchdown passes in multiple playoff games. Kurt Warner is the only other QB to do so.

7-2: Mahomes improved to 7-2 for his career in playoff games. The Chiefs were 9-18 in playoff games before he became the starting quarterback.

89: Dawson Knox set Bills single-game playoff records for receiving yards (89) and touchdowns (two) by a tight end in the win over the Patriots. He has four career receiving TDs in the playoffs, which is as many as every other tight end in Bills franchise history combined.

DEFENSE

3: Bills defensive end Jerry Hughes recorded a sack against the Patriots, marking his third consecutive playoff game with a sack and tying Von Miller for the longest active streak. Hughes' seven career playoff sacks are third-most in Bills franchise history and tied for third-most among active players.

SPECIAL TEAMS
