You make a good point, but as fans who have watched Belichick and this defense for a decade and a half now, I'll tell you that discussions like this is typically how he approaches shutting down someone like Matt Ryan. It doesn't always work of course, but the generally philosophy is to find the "archstone" of the offense, the thing that holds everything else together, and scheme to take that away while trying to find the best individual matchups on all the secondary options.
The end result (when it works) is an offense that is forced to do things outside of its comfort zone. This doesn't usually lead to complete domination, but combined with the other prevailing tactic employed by ALL Belichick defenses (limit or eliminate big plays), it means that teams have to sustain long drives, convert multiple third downs, and do so keeping pace with the Patriots offense, all without the use of their safety blanket.
This is why you don't often seen gameplans against good QB's to consist of intense and consistent pressure on the QB himself. They don't always view that as the best way to take an offense out of its rhythm.
Now, all that said, what you've indicated may be 100% correct: That scheming to take out Jones is just welcoming the other weapons for Atlanta to kill you. They're certainly the most versatile of the offenses we've faced all year. But right now we don't even know if BB is targeting Jones as that "archstone" piece. For all we know it could be the running backs, in which case Jones may have a field day while the offense is still kept in relative check.
This chess match is definitely the most interesting aspect of the game going in for me though. Great stuff if you're a football fan.
