Jones was a mixed bag in the Texans games, some very good plays, then the TD mistake.
This is what rookies do, they are inconsistent and you have to remember he missed some time with his shoulder injury.
Further, the shoulder injury from college also hurt his development as a player, he needs seasoning through experience.
Jones has all the ability and tools, he just needs experience by playing the position.
He will be fine and as others have noted he is not starting for a reason, if we have an injury or poor play elsewhere he will be thrown in the fire.
Jones is going to play regardless and the more experience he gets the better he will be in my book.
The kid has ability and intelligence, including the work ethic to get better.
