Keith,
I, like Ron VP, have had electronics training, both analog and digital.
As a fellow Tennessean, your analysis makes perfect sense to me.
However, I doubt a 'Gator can grasp the nuances of your expert opinion
of the situation -- same for the Gamecocks ('Cocks??? roflmao). Anyone
in a state that would hire Steve Superior to coach football is certainly
suspect. LOLs
