"That Halloween night was something where a lot of guys on the team dressed up and kind of just wanted to get away from all the seriousness and the grind that is college football season and go out and be kids again and dress up and just have fun," he said, without specifically addressing the pictures.
Manziel said winning the Heisman is something he dreamed about as a child, but that he hasn't spent a lot of time worrying about it or any other awards. No freshman has ever won the award given to college football's most outstanding player.
"I feel like that situation will play itself out, and whatever's meant to be will happen," he said. "I'm just doing whatever coach Sumlin and them ask me to do ... so we can take care of things in a bowl game."
But Manziel did admit that when he was younger he'd play college football video games and build a quarterback that would win the award as a freshman. Funny thing is, the players he made rarely resembled his 6-foot-1, 200-pound frame.
"When I created a video game player I probably made him 6-6, probably 230 pounds," he said. "I definitely didn't make him my size. But I've played so many video games maybe a few times I did. But typically I would have made him look something like Cam Newton."
Newton was the last SEC winner of the Heisman, picking it up in 2010. If Manziel comes away with the award, maybe somewhere in a small Texas town like the one he grew up in, a young boy will build a football player on his video game that does look like the A&M star.
Manziel has trouble grasping the whirlwind this season has been for him, and considers himself lucky to have had the opportunity to be in the position he's in now.
"This season has been incredibly surreal," he said. "It's beyond my wildest imagination. It's a true testament to how this team has grown every week, because without these guys none of my individual success would be anything."
