While the offense was the big story for the Tigers with Nick Marshall showing improvement, the three-star prospect said he saw some good signs on defense as well and got a good idea of what the scheme will mean for him moving forward.
"A-Day was great," Sullivan said. "I saw a lot of stuff that I liked, the game was pretty good. They scored a lot of points on the blue team. I was looking at some of the types of schemes and stuff like that and I like that I can kind of fit in that. The defensive schemes, I liked them."
"The crowd was phenomenal," he added. "Over 70,000 people there and it was crazy I can just imagine what the games will be like."
Solidly on board with the Tigers, Sullivan said his goal now is to help recruit other players to join Auburn's 2015 recruiting class between now and signing day in February. One of those guys is teammate and Alabama commitment, four-star defensive tackle Jonathan Ledbetter. Visiting for Auburn's A-Day and spending time getting to know the coaching staff, Ledbetter got a very good first impression of the Tigers but Sullivan said it's going to be an uphill battle.
"I'm trying to get people to come to the school and come up here when we graduate high school," Sullivan said. "I'm trying to get John but I don't know. I'm still trying to work on that. It was a tough time trying to get him to visit. had to talk him into it the whole week. Finally got him so that was an accomplishment.
"Well, when I bring them up here I mean, I just try and tell them to go and check on their own to see how it is and when they come back they tell me they like it. There's not really much I have to say."
