Defensive changes/personnel

[Whatever]

I would take the 4-3 talk with a grain of salt. Yes, I to think he will use it more, but defensive personnel is dictated by offensive personnel. If you keep throwing a base 4-3 out there consistently against 11 personnel, you'll get eaten alive. I do think he will use 4-3 more against the other AFCN teams, especially the Ravens who run a good deal of 12 personnel.

As for the Viper, perhaps he sees Stewart in that role? While I don't think he was asked to do much of it alin college, he definitely has the traits of a player that can rush the QB one play and run with a TE the next.
