Colts P Pat McAfee announced his retirement from football.McAfee announced he will soon begin writing for Barstool Sports. A two-time Pro Bowler, McAfee is only 29 years old but has undergone three knee surgeries in four years. Per the Indianapolis Star, McAfee had mulled retirement for "months, years even" and is "eager for the next chapter of his life." McAfee set a franchise record and led the NFL by averaging 49.3 yards per punt in 2016, but said he played in knee pain for "most of the second half of the season." McAfee doubles as a stand-up comic and has spent his free time writing screenplays and poetry. He was also openly critical of GM Ryan Grigson following Grigson's firing.Source: Indianapolis Star
