But Marvin Harrison Jr., their talented second-year wide receiver, is facing high expectations after an uneven, but promising, rookie campaign. His father, after all, is Marvin Harrison, the former wideout for the Indianapolis Colts back in the late 1990s and 2000s.

Peyton Manning and Marvin Harrison Sr. were one of the best duos in the NFL during their playing days, and Manning met up with Harrison's son this week.

Harrison Sr. played all 13 seasons with the Colts, totaling 1,102 receptions and over 14,500 receiving yards. He is a Hall of Famer, an eight-time Pro Bowler, a three-time All-Pro, and a Super Bowl Champion.
