I keep going back to what Mike Pettine said when he took over the Brown head coaching job regarding installing his defense

I think it's happened quicker here because I think it's a smart group,” Pettine says, comparing the install to last season’s with the Bills. “I'm not saying we were dumb in Buffalo—far from it—but this is a group that I think processes, as a whole, very quickly.”
When you compare that statement to the dont think but go mentality of Jim Swartz defense that the Bills seem to play better in then is it fare to say that our defense especially on the backend, might not be smart enough as a whole to run his defense.
If this is the case then either we need to get smart players or find enough defensive system to cater to our personel.
