That gamble has paid off and the sophomore has been getting lots of attention from across the country.
"It's been busy this spring," Grigsby told JCFootball.com. "I'm hearing from lots of schools from a lot of different places. My older brother, A.J. Grigsby, got a full ride from Kentucky and one of their coaches (running backs coach Ron Caragher) said he knows about me and he'll be watching me this fall. He said he likes my film a lot.
"The University of Illinois stopped by and they told my coach they liked me. Another school that said they liked my film was Oregon State and Washington's coach was here before May 1st so I didn't get to meet him, but he told my coach he liked my physical skills and my leadership out on the field. Then (Washington) sent me a questionnaire and I filled that out and sent it off to them.
"Ever since my coach sent out my tape, I've been hearing from a lot of schools that say they are looking to bring in a JC back. Coach (David) Watson from USC was by and said they want to bring in a JC guy to carry the ball so they will be looking at me as well."
Grigsby (5-11.5, 204) had a couple options heading into his senior season at Paramount High School in Los Angeles. After rushing for 1,300 yards and 11 touchdowns as a junior, he was offered by both Utah and Boise State, but he suffered a hairline fracture in his ankle six games into his senior season after rushing for 963 yards and nine touchdowns and his offers were pulled.
"They offered me partial scholarships, but I'm from a single-parent family so I couldn't afford to go to those schools and that's why I chose UC Davis because they offered me," Grigsby said. "I enjoyed my time there. I learned how to study and behave as a person and a man.
"After a big spring game I got the plaque saying I was the ‘Redshirt of the Year' and that was pretty special too, but I always wanted to see if I could play at a higher level so I decided to go to Sac City and see what happened."
All he did as a freshman for the Panthers is rush for 668 yards and five touchdowns on his way to the 1st Team All Nor-Cal Conference and leading his team in rushing. Now he's out to show that he can play for anyone.
"All these schools say they like my running style," Grigsby said. "They like how tough I run and how I'm a north/south guy who has speed."
A workout warrior, Grigsby was heading for his second workout of the day when JCFootball contacted him, saying he and his friend, current Washington safety C.J. Wallace, were going to the gym right after he finished his interview.
"I like Washington a lot," Grigsby said. "I'm going to try and get up there for a visit during the season to see C.J. play and see the campus and the school.
"I want to take some visits before I decide, but I need to wait for them to let me come on official visits because getting to the different schools is tough money-wise."
Grigsby said his top seven, in no particular order were, Washington, USC, Kentucky, Illinois, Minnesota, Virginia Tech and Boise State.
"I want a school with good academics because football doesn't last forever," Grigsby said. "As far as football is concerned, I want a powerhouse team that runs the ball a lot and a coach that says ‘I want you to play for us' because I will only have two years left. I need to make the most of them."
Grigsby just received his AA degree last week and will be able to enroll during winter quarter at whichever school he decides to commit to. He wants to major in Sociology and minor in Communications.
