An early commit to Boise State, he's also become one of the more heavily recruited cornerbacks in the region.
And if his performance at the Stanford NFTC last weekend, like it was a year ago, with a strong junior season in between, is an indicator, it may get even busier for him.
"I've got 11 offers and everyone is coming hard after to me," said Rios. "But I'm still a solid commit to Boise State. They were the first place that sparked my interest. I love it out there."
Rios is taking some unofficial visits and trips to college campuses this spring and summer, though.
"I'm visiting a lot of campuses and going to a lot of camps as well," said Rios. "And I will be taking all five of my visits. Boise State will definitely be getting one of them."
The rising cornerback, who will be in the Scout 300 in the next update, said that Boise State is recruiting him hardest, with UCLA, Washington and Washington State right behind the Broncos.
"Me and Coach (Marcel) Yates have a real close relationship," said Rios. "I know he'll make me an all-around complete player to compete at the next level. I went to their Junior Day and their Spring Game and loved it. I'm a solid commit, I keep my word."
His teammate and close friend Robert Ash committed to Boise State a year ago, and thwarted off the advances of other schools.
"Robert is not really recruiting me, he knows it's up to me," said Rios. "But we're real close friends and my bond is pretty close to Boise, so I'm still solid."
Rios said that he was surprised so many schools have offered him, especially once he committed to the Broncos.
"It actually did surprise me," said Rios. "Coach (Ryan) Gomes always told me, ‘Marcus you'll have 15-20 offers and the whole Pac-12 would be knocking on the door,' and it's exactly like he said."
