"I knew he liked Florida a lot, that was one of his things," according to his current head coach Marty Lee. "But, like every kid, even though you grew up a fan, you want to make sure the program is heading in the right direction. I think with the stability of the defensive staff and what Will (Muschamp) is doing up there, it was a fit. Muschamp believes it doesn't matter who you are, you have to be ready to compete. If you are a freshman or a senior you are going to play. That is the same attitude we have at First Coast."
Coach Lee said that although McMillan could hardly contain himself, his unselfishness played a part in why he waited.
"He went on a visit with his mom," Coach Lee said. "They really liked it and kind of made a commitment (Saturday). They wanted to keep quiet about it and not steal anyone's thunder around here for national signing day. It started leaking out a little bit and so he said he was ready to go public with it.
Coach Lee also says that McMillan is a dedicated young man and his work ethic has paid off with a chance to play elite talent next January.
"He is very excited and glad this is behind him," he said. "Now he can concentrate on his offseason and prepare for this senior season. He has already been invited to the Army All-American Bowl. He is going to see what he can do about possibly graduating early and see if he can enroll in Florida in January. He is ready to be a part of the ‘Gator Nation'.
"He had 43 division-1 college offers. He grew up a Gator and this is kind of like a dream of his. He is excited about what is going on at Florida and that is why he wanted to go ahead and make his commitment."
Lee loves McMillan's attitude both on and off the field.
"He's an outstanding young man and always has a smile on his face. He has a great disposition about him. He's a player when he walks on the field and a leader in school.
"He can read very well and he can adjust sets on the run. He will be our defensive captain and make all of our defensive calls. He has a very high football intelligence about him. When he runs, he runs with a force downhill. He also has the speed to run and cover in open space and that is what makes him such a big commodity."
First Coast has had a current streak of players that have gone on to rival schools, several to Florida State, one to Alabama, and others. However, the coach is proud of the history the school has with Florida as well.
"He is going to represent Florida in a great way, following in the steps of Reggie Lewis and Ryan Stamper," he said.
