"When we got here, Coach Miles told all of us freshman to be ready to play," explained Mills. "He told us that our number could be called at anytime and we need to be ready to help the team.
"We have to be prepared and be real serious about learning everything."
The true freshman has a lot to learn before he suits up in the SEC, but Mills is a quick study.
"It's all been a learning process," said Mills. "I was a little late getting here, so I was a little behind.
"I am catching up now. I am learning the scheme and the playbook."
The four star freshman corner reports that he has learned to lean on the veteran leadership in the secondary, but one player has really taken him under his wing.
"I have learned a lot from Tharold Simon," said Mills. "He has taught me the right things to do and where to be and all of that.
"He has really helped me a lot."
The physical part of football comes pretty naturally for Mills.
His efforts now center around getting the mental aspects of the college game under his belt.
"I need to stay in the playbook," said Mills. "That's probably the biggest thing for me.
"I am listening to my coaches and trying to get better everyday.
"I just need to be sure that I know where to line up and know what all I am supposed to do to help the team."
