"I just felt like now was the right time," said Tillman of his decision to commit to Mississippi State. "I haven't spoken to Coach (Dan) Mullen yet, but I have talked with Coach (Deshea) Townsend and Coach (David) Turner.
"I have a great relationship with Coach Townsend and I probably talk to him the most of all of the coaches.
"Coach Turner told me that they're going to be losing like eight defensive lineman and then three the next year. He said that they are going to have a need for me."
Being needed was a big part of the equation for Tillman when it came to Mississippi State.
"I feel like Mississippi State is a football team that is on the rise and it's a great school," said Tillman. "I think they really want me there and they're not just telling me a bunch of stuff.
"I know they need me to come in and play for them and that they really want me to be a Bulldog."
In addition to football, Tillman has found a lot to like about the Bulldogs off of the field as well.
"I love it over there on the campus," said Tillman. "Both of my parents love it there too and that was important to me.
"They have my major and I know what a great school Mississippi State is. I know that I can achieve all of my goals over there with football and academics."
The Bulldogs were one of several teams to extend an early offer to the Alabama standout.
"I have offers from Mississippi State, Louisville, Kentucky, Ole Miss, Jacksonville State and Alabama State," said Tillman. "I just felt like Mississippi State was the best place for me. I am about 99% sure I am going to the game this week and I am excited about getting over there."
Tillman is the eight verbal pledge for the 2016 Mississippi State signing class. He joins the class along with fellow Alabama native Dee Nalls of Fayette County High School.
