explain what is the perfect running style for Jones offense?
bc what you described after that sentence basically describes Every very good Running back
I stayed general in my post. Specifically - he is one cut and go instinctively with less lateral moves. When he makes moves he naturally does them moving forward with good body lean as compared to dancing a lot. The fit for the offense if you review Jones' schemes, which I have, is that the zone blocking schemes Jones utilizes have a lot of quick traps and counter style blocking that emphasizes angles. The back needs to be quick from the hand off, read the block at the assigned gap and go. As an example Neal could be great in this offense if he stops trying to go outside. He is a quick, one cut and go guy that has improved his ball security.
Other zone and power blocking schemes are slower developing, like Pittman's zone scheme. The back needs to be stronger to break arm tackles, more patient, or have the lateral moves to break the run.
Ford has very good hands for ball security and pass catching. His first step elusiveness will be good in the open field on passes. He has the extra gear for top end speed as well. Some of the others - Kemp, Barber, etc. - not so much. Kamara has it, but is more of a blend of a slot and RB.
Finally, he does not shy from contact. That is needed for Jones' offense as it is primarily between the tackles running and has occasional blocking responsibilities on passes to pick up blitzers. Some of this is obviously not unique to Jones' offense. However, the package of it and the strong emphasis (55-60% of all plays) on the run game is. Kamara could not hold up to that many carries and running inside IMO. Kemp, Barber, etc. probably could hold up, but don't have the quickness and instinctive elusiveness of Ford IMO. So their ypc would be less.
