To date, Grandstaff has picked up scholarship offers from Florida, Ohio State, Oklahoma and UNLV. He also has entertained interest from Notre Dame, Xavier, Virginia, Texas, Texas A&M, Alabama, Georgetown and North Carolina.
"It's been kind of crazy," Grandstaff told Scout.com. "There are a lot of schools coming at me. I'm just trying to handle it and all the other stuff will come. I'm really just letting it all pan out."
This past weekend Grandstaff took an unofficial visit to Florida for their game against Kentucky.
"It was great," Grandstaff said. "It was fun. The coaches and stuff there were cool. The fans were great. The atmosphere for that game was crazy. It was just a really good time."
"Right when I got there [Billy Donovan] was talking about how they needed scoring in my class and he thinks that I'd fit in their system and he said he wanted to let me know that I have an offer from them," he added.
What did Grandstaff learn the most during his trip to Florida?
"I learned from watching them play against Kentucky that the ball moves a lot," Grandstaff said. "They move the ball around a lot, especially compared to Kentucky where the ball sticks. With them the ball moves around the perimeter and they do a lot of ball screens a lot. I really liked that a lot too."
Grandstaff said his visit to Florida moved them up his list.
"They are definitely up there with my favorite schools right now," he said. "I just think the style of play for me and his player development and how strong the guys on the team are. Their strength coach is really good. It's a really good school and I could see myself there potentially."
Prior to visiting Florida, Grandstaff took a trip to Oklahoma for their game against Texas.
"It was good," he said of the visit. "It's only a three and a half hour drive so I can really make that trip pretty easy. It was really fun. They surprised me a lot. Their fans were big too. They are having a really good season and they've turned it around. Their style of play is really good with how I play as well."
Grandstaff said despite decommitting from Oklahoma State that they are still actively recruiting him.
"They came to the school two or three weeks ago," he said. "I still talk to them sometimes. I haven't talked to them as much as when I was committed and stuff because they know other schools are coming after me, but I still talk to them quite a bit."
At this point, Grandstaff, a 6-foot-5 wing, doesn't have any other visit dates planned, but did say that he might go to Ohio State in April and would like to try and visit Oklahoma and Oklahoma State again.
