I don't why people think Jones is so bad against the run. Yes, he sucked early in the season, but who didn't. In his first two years in the league he wasn't bad at all vs. the run. And he did pretty well vs. the run last week.
I chock up a lot of his problems from playing in a position that doesn't fit him and possibly trying to do too much since they were struggling in a lot of areas. Because one of the things that surprised people so much about the guy early in his career was how well he did vs. the run since everyone thought he was just going to be a pass rush specialist.
