At 1 PM, with his teammates, coaches, family and friends, school administrators and a few local media outlets looking on, Grinter put pen to paper - in this case to a binding national letter of intent - and signed on the dotted line to join Bobby Petrino's Louisville Cardinals.
"He did everything for Fairdale - ran the ball, caught it, returned kicks, played defense. The only thing he didn't do was play offensive line and that just because we ran out of time or he probably would have done that too," Bulldogs coach Mike Gossett said.
So why Louisville for Grinter?
"Why U of L?," Grinter asked. "Because it's where I thought I would fit in the most. I'm excited because I always wanted to be a part of a winning program and Louisville seems like it's the place."
Grinter, whose father Maurice Morris was a Fairdale basktball standout in the early 1990's, said his family was happy he decided to stay home and play for Louisville.
"It was important to my family to stay at home but they basically told me to do what I wanted to do," Grinter said.
Grinter rushed for over 3,200 yards at Fairdale and also made 19 career interceptions. He was one of the first players this fall to verbally commit to U of L and that decision kept most of the other schools that had been pursuing him from continuing to do so - that is all but one - Louisville's in-state rival, Kentucky.
"UK did [continue to recruit me] but after I committed most schools just backed off," said Grinter.
Like his father, Grinter is also a standout on the basketball court. He's averaging 20.5 points this season and hopes to play sports next season at U of L.
Fairdale baskteball coach Lloyd Gardner had high praise for his teams top performer.
"I've known Maurice since he was one-year old," Gardner said. "He's a fierce competitor and has a desire to excel. Coach Pitino told me he would give Maurice the opportunity to play basketball at U of L and that was one of the reasons he chose Louisville."
Whether or not Grinter actually plays basketball at U of L remains to be seen. But Gardner said that regardless if his standout plays both sports in college, Grinter made the best decision for himself.
"We think he made the right decision to attend U of L," he said.
