back to OP, Sumlin isn't going anywhere this year. Hyman was the Steve Patterson Lite, with very little interaction with alums and the media. Same as UT, you have to know the Big $ Ags by the first name, and be an active community/promoter of the Athletics department on all levels. While he was at and around the sports, he was MIA as far as promoting and pressing the flesh with key folks. A very good guy personally, but a bad fit at A&M, where politicking is # 1(b) after sports.
Sumlin is feeling some heat, certainly...but you don't hire an AD (Woodward), and a new OC (Mazzone), or this late in the recruiting cycle (Jan7) if you are preparing to fire the HC. Watch for the heat after 2016, especially if the Aggies go 8-5 again, which very well could happen.
