Jones has been one of the unsung heroes on the 49ers’ defensive line. He doesn’t play a ton of snaps, but he’s a vital component to their run defense. That run defense needs to be at its best against Baltimore. Jones generally plays in the neighborhood of 50 percent of the snaps. The 49ers may want to get him on the field more often than that Sunday to try and turn the faucet off on Baltimore’s rushing attack.
