Bill Belichick has spoken out on the debate over whether or not Kansas City Chiefs quarterback Patrick Mahomes can achieve a record similar to that of legendary New England Patriots quarterback Tom Brady.

As noted by ArrowheadPride.com, Rice tight end Graham Walker is taking part. He’s the half-brother of Chiefs quarterback Patrick Mahomes. The son of Pat Mahomes Sr., Walker transferred to Rice last year, with the initial plan to play receiver. He later switched to tight end.
