From Adrian McPherson's Pro Day
If this is a repost sorry
coach Turk Schonert ran the second part of the throwing workout. To measure McPherson's true arm strength Schonert had him throw flat footed with his toes on the line. The result was a pass which sailed through the air 72-yards.
He threw a 70 yard deep out that was perfect on the money..... out of 65 passes his first 30 were on the money the 70 yard out was one of the later passes thrown
He ran a 4.51 40 on a grass field
