Shockwaves were sent through the NFL world and sportsbooks alike last Saturday night, when Indianapolis Colts star quarterback Andrew Luck announced he was retiring. Luck, the overall No. 1 pick in the NFL Draft back in 2012, is only 29 years old and just won the NFL’s Comeback Player of the Year award after leading the Colts to the playoffs one year after missing the entire season due to injury. Last season, he threw for 4,593 yards and 39 touchdowns with only 15 interceptions. But the physical and emotional toll of a number of injuries led him to decide that now was the best time to walk away from the game. While Luck’s surprising decision certainly will cause immense ripple effects throughout the NFL, it also sent shockwaves through the entire sports betting landscape as well.
