My guess is he's not gonna run.... If he does, I think he puts up 2 attempts in 4.6s. If JSN puts up anything in the 4.5s I'd be very happy.
my guess is that he doesnt run the 40 but runs at his pro-day
if his 40 time is sub-4.60 then i think he's gonna be fine
if his 40 time is sub-4.50 then i think you can forget about him being available at 22
i think 4.55 might be the sweet spot if you're a ravens fan who wants him at 22
