"A lot has changed over the last year," said Terry. "I feel my accuracy has gotten way better and the mental part of the game has greatly improved. Being a quarterback there is a lot you need to be mentally prepared for and not just physically prepared.
"Last year I would go into games not knowing what to expect from other teams. However, this year a lot has changed and I really believe I'm playing to my potential as I've got like a 75% completion percentage and 25 passing touchdowns and five rushing touchdowns. All the offseason work has been going real well as our offense is going real well as well as our defense. So everything is clicking."
While many wondered if Mark Dantonio and his staff hurried in offering Terry, the FOXSportsNEXT.com four-star (No.29) quarterback used it as motivation.
"I love proving people wrong," said Terry. "Everyone has critics no matter what sport they play. But it's a good feeling proving people wrong. However, I'm really not trying to pay too much attention to all of it as I'm still in high school and still young and learning the game. But it feels good to have a weight off my shoulder and playing to what I feel is my potential."
One recent change in the Spartans recruiting was welcomed by Terry as teammate Delton Williams pledged to the Green & White.
"I have a great relationship with all the other commitments to Michigan State already," said Terry. "But having someone coming with me from my city, my hometown, and being a good friend of mine is a major plus.
"Delton has been my main man since our freshman year on the football field and my go-to guy even as a running back coming out of the backfield as a receiver. It means a lot as I know he's going to watch my back and I'm going to be watching his. So it felt real good when I heard he was going to be part of the Spartan family."
A few weeks ago Terry made his first game day visit with the Spartans and came away impressed.
"I was able to visit for the Ohio State game," said Terry. "I'm also playing to return when they play Northwestern or Nebraska. It was just a great experience and my first game as in the past I've only visited for the spring game.
"It was great with College Gameday being there and the atmosphere and the fans. I would be walking around and the fans knew who I was and I can't wait to get back up there."
Despite the Spartans struggles on the field this fall Terry knows there is a lot of good in his future.
"I know they are going through some struggles and many felt they would be much better this season," said Terry. "The season is still not over as they've got Michigan this week. We lost a lot of offensive starters with guys like Kirk Cousins and three starting receivers. Everyone is learning the offense and there is a true freshman starting at receiver along with some injuries on the offensive line. But we still have a great defense and it doesn't matter if they lose as I know they are still a great team and I'm just ignoring all the critics."
While Terry is a strong verbal pledge, he stays in contact with the Spartan staff.
"I talk with (assistant) coach (Mark) Staten and (quarterback) coach (Dave) Warner like every week," explained Terry. "We talk and keep up to date with how things are going. I also talk with (head) coach (Mark) Dantonio a lot and have a great relationship with all of the Michigan State coaching staff.
