That is absolutely false. As far as Arm Strength and velocity go Brett Favre, Dan Marino, and John Elway are probably tops. I’ve personally clocked Marino throwing 68 MPH. And on top of his velocity he had the fastest release of all time.
Josh Allen has a strong arm. But to say it’s the strongest ever is ridiculous. It doesn’t compare to the three I mentioned. Drew lock has better velocity than josh Allen.
