its easy to look good when you have vilma,sean taylor,ed reed and the rest..
he is a good DC .he will hardly blitz..he comes from the jimmy johnson school of defense. base 4-3 and let your d-line cause hell..your linebackers will have to be safety-size cuz they will be covering alot in his scheme..its based on speed not size. not very exotic..vanilla defense but effective with the right players.
one thing that will fustrate you will be facing a running qb..shannon just didnt know how to contain one in his last years at miami (who the hell knows why)
he is an amazing recruiter when he wants to be..what sucks is that he lost alot of his connections to south florida..for some odd reason he just didnt communicate very well with them in the latter years.
but a good hire if given the pieces to work with..which i think he has at tennessee
