They'll mix it up, for sure, but I agree. As important, is whether the Patriots settle in with a fewer number of unique defensive lineups. Against the Dolphins, there were 47 unique defensive lineups which wreaked havoc on the Patriots. That may have been by design in the heat and humidity, but it sure was chaotic in the 2nd half.
In Patterson and Jennings, Matt Cassell has two good receivers. Revis can take away Jennings at the line of scrimmage more easily than Patterson, who could see a double team when Revis is not on him.
Without Peterson, the Pats should be able to stuff the run, and make Matt beat them with his arm. I completely disagree with Jim McBride's forecast of the Vikings getting 30+ against the Pats. I think the Vikings will struggle to get 1st downs, and we'll see the Patriots secondary have a superb game against a competent journeyman.
