Maybe. Beamer calling plays for those 2 games would be really interesting since he spent most of his career on defense and special teams. His offense experience is with TE & RB. He had NO prior experience calling plays.
Here's a quote from Beamer from The Greenville News after the Clemson game ""What a fighter he is, and he'll be the first to tell you we didn't coach well enough in the Florida and the Missouri game," Beamer said of Satterfield after the win at Clemson. "That is a fantastic defense we just played ... We knew it was going to be tough and ugly at times ... and Satt did a great job."
I don't know what's true but I'm suspicious of that rumor.
Edit: IF Beamer called the plays vs Tenn & Clem, he should have done it again in the Bowl Game as their offense sucked. That's almost an argument against the rumor of him calling plays against Tenn & Clem.
