Who's Florida's QB has had very little to do with Tennessee's last 3 losses to them...really doesn't matter who it is or to some extent how well and certsinly how consistently they play.
2013- Driskel went down to injury early while throwing a pick 6 and had a 1.6 QBR for the 1st quarter. He was replaced by junior Tyler Murphy who had no stats at Florida prior to then....he proceeded to look like the second coming of Randall Cunningham in leading Florida to the win. Of course, he was bad enough the rest of the season that Muschamp ran him off and he transferred to Boston College.
2014- Driskel was epicly, historically awful in Neyland for 3 full quarters. He threw 3 interceptions deep in his own territory, had 59 passing yards and finished with an 8.4 QBR. Treon Harris, who was a god-awful D1 QB, came in and didn't do much more. Combined, they were 13-27 for 76 yds, no tds and 3 ints....and we still lost at home before a sold out, rabid, orange and white checkered home crowd.
2015- prior to the last 2 drives, Grier wasn't very good...he was downright pedestrian at very best...12 of 25 for 134 yds, no tds, 1 interception. But of course, when it came time to win the game because he was playing Tennessee, he looked like Joe Montana....on the last 2 drives, he was 11 of 17 for 149 yds and 2 tds.
Therefore, one can easily conclude that it really doesn't matter who Florida's QB will be this year. It hasn't much mattered at all in recent history.
QB play has determined the last 3 games, but it has been our QBs, not theirs. Starting Peterman in 13, Worley getting stripped sacked deep in our territory in 14, Dobbs being afraid to throw it and also being strip sacked deep in our territory in 15. When Butch grows some balls and actually lets His QBs pass the ball against good defenses we'll see this series turn around
