For those old enough to remember, in 1999 Tennessee outplayed, and should have beaten Florida. Alex Brown for Florida, who had five sacks in the game, later admitted that the Florida defense was able to read Tee Martin and basically knew what every play was going to be. Of course this was obvious to anyone watching the game except for the Tennessee coaching staff and Tee Martin.
I bring this up because of what Hooker says at the 55 second mark; "Mitchel is locking in on the signals". When we have opposing coaches stating (anonymously) that our offense is pretty simple, a quarterback that recognizes defensive reads is crucial.
