Grissom, who is still looking to visit ECU's campus and tour the facilities, plans to take a trip to Greenville this summer.
On his visit, Grissom is looking to meet the coaches and ask them about what kind of playing time he could expect.
"When I visit this summer, I want to build a relationship with the coaches," Grissom said. "I also want to talk to them about playing time."
As a quarterback, Grissom is excited about having Scottie Montgomery at the helm, and noted that his playing style fits into Montgomery's system.
"I heard he's a great coach and that he's looking for a QB," Grissom said. "They are recruiting me as a dual-threat quarterback that fits into their system."
Grissom was also optimistic about the direction of the program and is excited to meet the coaches and see the campus.
"I think ECU is building a great program," he said. "I really like it and can't wait to get up on the campus and be able to talk to the coaches in person."
Grissom is looking forward to the transition from high school to college, but understands the difficulties that the transition presents.
"I am looking forward to bringing leadership and hard work, and building a relationship with the players," Grissom said. "The hardest part about the transition is being able to build a relationship with the players because I know it will take a lot of time."
In 11 games last year, the 6-foot-2, 204-pound Grissom threw for 2,694 yards, rushed for 625 yards and accounted for 39 total touchdowns.
