So you're saying he'll re-write the coaching manual for how running backs are suppose to run?
It's an interesting argument IMO...
There are guys who have succeeded with an upright running style... Hall of Famer Eric Dickerson being the most well known example of it...
But your right... There are reasons why they do things...
My biggest issue for him making it has always been his value to a roster... He needs to make himself valuable enough for them to keep... Because a K/PR needs to be able to stand up and be useful in another area... Which as he was going to be a RB... Made me worry about his ability to block.
That is still his biggest hurdle... He needs to learn the playbook and learn how to recognise blitzes and coverages... He can score 3 touchdowns in a game... But if he doesn't pick up his block and the QB gets blindsided he could be cut in an instant.
These other RB's have been playing the game for over 10-15yrs... So they have the benefit of all those years and have developed the instincts to recognise those things.
The QB has to be confident that the RB can pick up any stragglers that come at him..
