That's an interesting question.
I know a lot of Bama fans think Kirby has been negatively targeting the Tide during the recruiting process. The media has asked CKS many times about his recruiting approach and his response has been consistent from the beginning. He believes UGA sells itself (ranked nationally as the 13 best public university, great facilities etc., etc.), therefore he doesn't have to negatively recruit. In post commit interviews from players over the last three years that narrative seems to ring true.
Regarding the selling points to Trey, I would suspect they're as follows:
1. Early PT - Kirby plays'em young. Therefore, if Trey comes to Georgia he will play.
2. PT part II - It's anticipated Holyfield will enter the draft after this season, increasing the opportunity for early PT.
3. Zamir White - He suffered a second ACL on his other leg before the start of the season. There's a lot of uncertainty about whether he can get back to HS form.
4. OL - Pittman is building a beast of an OL, with 5*'s backing 5*'s. There's a ton of talented depth to run behind, which is very important to 5* RBs.
5. Academics - Kirby will pitch academics to Trey. "Come to UGA and get a great education."
Finally, there's the Nolan Smith factor. Smith also plays for IMG and from what I've read he's relentless recruiting guys he wants to play for Georgia. He's in both Sanders and Neal's ear. If you look at the CB's they trend toward Bama, so we'll see how it goes.
