My understanding re the contract situation is that there is a final 53 man roster. Normally about 40 or so are under contract . JH then has to compete with say 50 recruits for the final 10 spots. As players get cut etc , they then move from club to club making the competition pretty fierce
He certainly has the athletic attributes to do well, but I don't think anyone has made the jump from another sport into the NFL unless hey were in one of the kicking roles. Going to be a very interesting journey, and I think may get to try out for more than one team as he searches for a roster spot. Don't forget he is going against players who have played rhe sport since they were 8, and know how to interpret the play books
