re: Who was the tall black chick on SH sidelines?

Brent Musburger, analyst Jesse Palmer and reporter Maria Taylor are the SEC Network’s lead Gameday commentating crew.

and she is a host on the very informative SEC NOW:

SEC Now, the nationwide network’s news and information show (airing Mondays and Tuesdays at 7 p.m. ET; Thursdays and Fridays at 9 p.m.). The team that will be rotating anchoring SEC Now: Dari Nowkhah, Maria Taylor and Peter Burns.

She really got Miles to open up about the QBs, saying on Friday night's show that Miles said that Harris had such tremendous arm strength and overall talent that he would always win head-to-head matchups with Jennings 10-out-of-10 times in practice and he felt that all he lacked were some game reps and that he intended to get him plenty of those over the next two weeks.
