Ed Reed retired more than a decade ago back in 2015, which officially means he played at a time before most current NFL players were drafted. Patrick Mahomes for example, was drafted in 2017, so Reed never had the opportunity to play against the three-time Super Bowl champion.
That doesn't mean that Reed hasn't cracked the Mahomes code and identify his weakness(es). He is, after all, a Hall of Famer and one of the best defensive backs to every play the game. So if there's anyone out there who might be able to figure out Mahomes, it could very well be Reed.
