Don't get why people think he won't be able to pick the game up.
Let's assume he's on the offensive side. The coaching staff & quarterback call all the plays. They practice these plays at training until they do it in their sleep. So as soon as Hayne hears "24 blah blah red blah" he knows exactly where he's running to and the likeliness of him getting the ball. All he really has to learn is terms the coaching staff are using. It's not that difficult a sport to learn especially if your training is a fulltime job (even more so then it was in NRL). And it's not like teams will pass over him because he has to learn it, every year teams bring in new players to the organisation who also have to learn the playbook.
Lack of instincts may hurt his chances, but the need for those lifetime developed instincts are rare as well.
In terms of athleticism, yeah there may be some younger Americans who are more athletic, but in US sports they have their minimum athletic testing scores, which if you qualify within the tests it really doesn't matter if there were guys who could run 100m 1 second quicker than you, you move on to the next lot of assessments. And I reckon this is why he has gone, he has been through some testing was within the minimums.
The main factor in whether he makes it or not will be whether there is a team looking at him and what he brings fits their criteria and that there is no other option that fits that criteria better. To which I don't think (haven't seen any college football recently) there would be any other player with identical attributes, plus I think Hayne's only criteria is to actually get signed, and very little to do with money. I reckon it's a small timeframe (probably late 2016) for him to mesh his attributes with a team's criteria.
I give him 50/50 shot
