"I guess I have known for sure that I was going to be on the team for about three weeks or so," said Simpson. "I got a call from the coach that is going to be my position coach.
"He wanted to introduce himself and congratulate me for making the team."
While many players were surprised with their selection, Simpson reports that he felt he had a good chance of making the All-Star squad.
"I was kind of expecting it to be honest," said Simpson. "I went to an OL/DL camp over at Mountain Brook High School and Coach Yeager from over there told me that he liked me and that I had a good chance of making the All-Star team.
"I got a call later telling me that I made the first cut and then our coach went to a meeting and I made the second cut.
"Then they called me and told me I made it."
Simpson is looking forward to representing his home state and getting to know some of his fellow Mississippi State commitments during All-Star week.
"It's going to be a lot of fun playing against all of them," said Simpson of nine Bulldog pledges on Team Mississippi. "It's a chance for me to show them what I can do and a chance for me to see what they can do.
"We're all going to be teammates for a few years, so I really want to get the win. I can hold that over their heads the next four years."
Recently, the talented defensive end had the chance to meet some of his future teammates when he attended Mississippi State's game against Tennessee.
"I had a good time at the game," said Simpson. "I got to meet Chris Jones and a couple of the other guys.
"The Tennessee game was the first one I have been to this year, but I plan on going back when they play Texas A&M."
Before Simpson returns to Starkville, he has some urgent business to attend to at Oxford High School.
"We have our last region game this week," said Simpson. "If we win this week, then we're in the playoffs for sure.
"If we don't win they we put it all in another team's hands.
"We play Pell City this week. On paper people are going to say that we should win, but we aren't overlooking them.
"They are well coached and we're going to play over there at their place.
"Anything can happen, so we'll have to play well."
Simpson reports that opposing teams seem to have a working knowledge of him and his abilities.
"I never knew what type of impact making an early commitment would make," said Simpson. "People know who I am now and a lot of teams have been running away from me.
"That's fine. I am just working hard and trying to help my team anyway I can.
"I want us to go as far as we can in the playoffs."
