Richt generally was resistant to playing freshman at UGA, especially a freshman QB. I know Richt played a lot of freshman at Miami last year, but I think that's largely because he was a 1st year coach and the freshman were his recruits who fit his system.
I don't know about his time at UGA, but it seems like now he and his staff are taking the philosophy if you show you are the best at your position it doesn't matter if you are a freshman or senior you will get to start. Lots of freshmen got to start last season because the roster was depleted and those guys earned the position they got over the rest of the field. If Grace and AQM had not gotten in trouble you would of probably seen at least 1 less freshman getting starting reps though they would of certainly gotten reps to spell other players or in case of injury.
If I had to guess they are telling recruits that this season was proof that those recruits can earn a starting spot, but the spot will not be given to them in the recruiting process. Get in early, learn the play book, get up to the level physically and you can have a good chance to start as a freshman.
