I don't think we can under-estimate what a Keith Brookings brings to our defense.
Leader? Hell Yes!
Brookings was "The guy" for the Falcons for over a decade. The Cowboys signed him for his veteran leadership. He is a leader of men....ala Peyton Manning...for our defense.
Let's face it....our defense the last 5-7yrs have had DJW and Champ....good guys...very good to great players.....but leaders? Maybe...but, obviously not what's been needed.
I agree with working DJW in b/c of his talent...but, not at the expense of our current defensive chemistry!
