"The all-star game was great," Miller said. "I played against some good competition and it was my first time playing outside linebacker in a game. It was great to experience because I did much better than I thought I'd do."
As a senior, Miller racked up 17 sacks to lead the Poets to a third consecutive Class 1A state championship. In the final game of his prep career, Miller made the switch from end to outside linebacker and made the transition appear easy.
"I started and I was named team captain," Miller said. "I led the team in tackles and I had a fumble recovery."
Miller originally gave UNLV a verbal commitment but changed his mind when Louisville offered a scholarship just before national signing day. Louisville assistant Larry Slade recruited Miller while at Tennessee and played a big part in Miller's decision to sign with the Cardinals.
"They definitely like my pass rushing ability," said Miller. "I'm definitely going to be playing outside (linebacker). I played defensive end in high school so I understand linemen's tendencies. A lot of coaches commend me on my pass rushing ability and say I have a natural bend to get a sack."
Miller will arrive in Louisville July 8. He's looking forward to making the transition from high school all-star to college freshman.
"Everything was basic in high school and now we're going to have a big playbook. But after I get that down it's about being athletic," Miller said. "I'm going to put all my effort into being a great linebacker and a great football player for the Louisville Cardinals."
Miller, a 6-foot-1, 207-pounder who has clocked a 4.7 40-yard dash, has been working hard this summer to prepare himself for his first year at Louisville.
"I've been in the weight room and preparing mentally," Miller said. "I've been watching a lot of film on players like Jelani Jenkins to see what you have to do to become a great linebacker. I'm going to work hard when I get there, study the playbook and get in the weight room."
Miller played alongside Louisville linebacker signee Mike Privott in the All-Star Football Classic and the two freshmen will have an opportunity to compete for playing time when fall camp begins in early August.
"I already feel like I'm part of the Louisville family," said Miller. "I feel I'm ready to go and get there and play football. I expect to go in there and work hard. There is nothing given in football even if you're a five-star recruit. They didn't guarantee any playing time. Ultimately it's up to me if I'm going to play. If I see the field this year or next it's going to be great either way."
