One change they made on the D-line besides Brian Young taking over for Grantham was they gave a mandate to the DE’s to get to the quarterback (funny right?)
Apparently before with all the exotic stuff they were trying the players didn’t like it.
I think Allen was tired of getting killed by running QBs and started to employ the same rush techniques against immobile QBs like Cousins. I'm not sure yesterday is the start of something better unfortunately.
