Herm Edwards and John Lynch know each other well and the 49ers general manager trusts the Arizona State head coach.
Edwards also knows new 49ers receiver Brandon Aiyuk well, having coached him during the past two seasons at Arizona State. Aiyuk -- who the 49ers selected at No. 25 overall in the 2020 NFL Draft -- didn't blow people away with his 40-yard dash time at the NFL Scouting Combine. That 4.5 40-yard dash time ranked 21st among receivers and had some doubting whether or not Aiyuk was a first-round talent.
But Edwards knows the difference between test speed and game speed, and he likened Aiyuk's game speed to that of the greatest to ever do it.
