He knows that some of these groupings will be necessary to adapt to certain D schemes that will try to mimic the Bears, Lions, and Patriots of last year matchups. And McVay seems determined to keep his guys sharp for when they will be required to counter-attack those schemes.
It also might give opposing DC’s pause as they are forced to prepare for more and different Ram O sets.
Meanwhile, McVay will continue a very heavy dose of 11 personnel grouping and with good results.
The chess game continues! Lol.
