I don't think this is the end of the world. Hopefully it motivates Jones to be better with discipline and learning his assignments. I'm sure he will be back in the mix soon and I'd be surprised if he isn't starting again by the end of the season. Let him use the benching as a learning opportunity and as an opportunity for motivation to get better.
I still think Jones will be good going forward. I'd like to see him really hit the weights in the offseason. He shows flashes, and I think some experience and some weight training will get him to his potential.
