There is no "3 QB Merry Go Round", so get your facts straight. The only time the 3rd QB has played this year was late in the blowout second game. It is the belief of most fans now that Lambert has won the starting job and will take all or most of the snaps this week barring injury. Inserting Johns against UCLA had two fold benefits. He got experience if needed going forward and because of his interceptions (in his first start) Lambert got the opportunity to watch. It just so happened that Johns lit it up and earned at least the opportunity to play some the next game. His snaps decreased sharply against UL.
Also, I think some of you are misguided on Virginia's speed. This has been the best of all London has done since becoming HC. He has increased team speed markedly. I wont say we have as many speedsters as FSU, but we do have more than we used to, and we have a few that are burners.
