"I only thought about how big of a game it was and what it might feel like to be one of those players," Miller said. "I wasn't thinking that I would soon be a part of the program because my recruiting process had hardly started."
As it turned out, the Georgetown (Ky.) Scott athlete would not get too deep into the recruiting process. A week and a half after picking up his first offer from Western Kentucky, a Michigan State offer quickly ended his recruitment less than an hour after he received it Thursday.
"The offer, to be honest, was a bit of a surprise," he said. "It was based off my performance the past couple days at camp, which the coaches told me they found really impressive and they thought because of that I was worthy enough to get an offer to become part of the program.
"The rest of the day has just been kind of crazy. … It has been the best of day my life."
The 6-foot-3, 195-pound Miller said the decision came quickly for a few reasons. For starters, his father, John, was a defensive back in the 1980s, but the younger Miller said it was more than that.
"It was because growing up, he brought me to tons of games and he was able to show me just how great of a place it could be," Miller said. "He was the one who exposed me to all of it and I just fell in love with it at an early age. From 8 years old on, it was just my dream to play here and say I was able to do the same thing as my dad.
"It has the same feeling 10 years later. I knew as soon as Coach (Mark) Dantonio said we are going to offer you. … I knew right then it was done. No matter who else offered me, it was still going to be the place I called home no matter what."
Dantonio informed Miller he had an offer Thursday as a defensive athlete – either to play outside linebacker or safety – and said to take some time to think about it. So he talked with his mom – who also attended Michigan State and was in East Lansing with him – and call some relatives but, most importantly, his dad.
"When I was talking to my dad, we both knew this was it," he said. "He was fired up for me as a player and then as a dad, he couldn't be more excited that the opportunity that he got to play college football is the same place I'm going to get mine."
The Spartans worked out Miller at both linebacker and safety while at camp, the places they envision him playing when he arrives on campus.
"They think I can move into their weak outside linebacker position or possibly a safety spot," he said. "Once I get there, they think I could play safety at 205 or I could bulk up to 225 and play linebacker because of my frame.
"I feel like as a player whatever they ask me to do, I am going to be able to do with the right amount of time and conditioning and weight lifting. I just think from a skill standpoint, I am going to be able to do it all for them and I'm open for anything. Whatever they see fit, whatever will best help the team."
At whichever position that may be, Miller just wants to be get on the field and contribute in any way possible, including special teams.
"I'm someone who wants to play special teams," he said. "I am really going to work really hard to get on special teams as early as possible or any chance to get on the field. I think I can really help the team and do that and that's something I like to do.
"As a position player, I feel like I'm someone that you turn me into three different positions and I can still help a football team, whether that is outside linebacker, strong safety or free safety. I would open myself up to do anything to get playing time to help the team."
Miller is the sixth commitment in the class of 2015 and the second in the past week, joining Jackson (Mich.) Lumen Christi's Khari Willis as recent commitments.
