But schools haven't let up with the four-star, ranked No. 5 in the 2018 class.
"It's something I never expected when I committed," said Rising. "I'm enjoying it though. Its fun to be on the phone with coaches. It’s a blessing and a curse, I guess, but I’m glad I have that opportunity. It has been fun."
The Sooner commit said that a few schools in particular have been staying in steady contact with him and ramping up their efforts.
Texas and new coach Tom Herman have a connection to Rising and his family.
"He's from Ventura County and he played at Cal Lutheran where my dad played and my dad knows him," said Rising. "My dad knows Coach Herman would take care of me and we've talked about that here and there.
Oregon has also picked it up since new coach Willie Taggart arrived in Eugene.
"I've talked with Coach Taggart but it's been more Coach (Mario) Cristobal and Coach (Marcus) Arroyo," said Rising. "They hit me up on my phone a lot but I get the occasional text from Coach Taggart."
Michigan has been recruiting Rising for a couple of years.
"It has been mostly Coach (Pep) Hamilton lately but I get the occasional text from Coach (Jim) Harbaugh that wakes me up early in the morning."
UCLA has been on Rising for a long time as well, and with new offensive coordinator Jedd Fisch now in Westwood, he's kept the relationship he started with Rising at Michigan going.
"I've been talking to Coach Fisch a little more lately," said Rising. "We talked when he was at Michigan but we're talking a lot more now that he's at UCLA. But I'd say with UCLA, it has been even more with Coach (Jim) Mora and he's been recruiting me hard lately too."
But despite the efforts of the others, Oklahoma continues to hold Rising's verbal.
"I'm all in with Oklahoma," said Rising. "It would be tough to have a reason to not go there, I can tell you that. I love the coaches and the opportunity there."
Rising said his relationship with offensive coordinator Lincoln Riley is a crucial part of his recruitment.
"I talk with Coach (Bob) Stoops a lot, but it's mainly with Coach Riley. He's taken over my recruitment and we have a great relationship. We talk all the time."
With Baker Mayfield graduating after the season, Rising knows the opportunity to play as a true freshman is possible.
"Baker Mayfield is gone after this year and I'm graduating in December so I'd leave in January and have a chance to compete for the starting job and that's a big thing for me," said Rising.
In the meantime, Rising is looking to bounce back as a senior after injuries cost him much of his junior year. He looked good at the adidas 7v7 National Championships in Las Vegas last weekend and will be at The Opening Los Angeles Regional this weekend.
