Yes, you do. Can you actually prove the MYTH of third and Chavis or are you just parroting what others have said and you feel about some plays back then? You are so certain that it's a verifiable fact, then show some actual stats vs other coaches of his era at UT.
After you neglect to do that, then explain if he was so bad on 3rd ... why Les Miles snatched the man up instantly and has shown one of the best defenses in America every season since.
Our defense for the past 4 years looks NOTHING like any defense John Chavis put on the field as DC from 95-08.
So, yes you do need to say more.
