Rodgers said it in the post-game... The Bears were rolling coverage to Adams/Cobb, and that left Jones/Rodgers in several one-ones. They were challenging them to throw elsewhere, and #12 made them pay by either pinpointing an seemingly impossible pass or running for chunks himself.
This, and we saw it last year when Adams had his big games. I doubt Jones quite ranks as "solid" these days (though still a strong "decent"), but he's still a NFL-caliber receiver and with Rodgers and one-on-one vs. less than stellar DBs that's still a matchup win.
