This is nothing more than a depth move, but Van Dyke ran a 40 under 4.3 once upon a time.
According to Van Dyke's own Instagram page, he has signed with the Atlanta Falcons. He was drafted in the 3rd round in the 2011 draft by the Raiders (shocking, I know).
He has made no major contributions to the game since 2013 and has floated around the league since he got drafted.
I really don't have anything more to add. He seemed pretty happy about it, but I'll be surprised if he makes the final roster.
