Rewatching the game, and I see that Elam was in on the first couple of series and played just a bit in the 2nd half. I do not see him being hurt. I think it has to do more with going with a 4-3 today instead of a 3-4. We tried to get quicker DTs into the game.
On the long Florida TD by Del Rio to Callaway, you can actually see Elam bull rush the UF center and push him back a good 3-4 yards. He put his hand up when he was getting close to Del Rio, but unfortunately the ball had already been launched.
I also noticed on UF's first play from scrimmage, Elam managed to shed a block and be in on the tackle.
But that is pretty much all I saw Elam do today. Simply not enough to justify playing him if the point was to go with a quicker 4-3 alignment.
