But coaching turnover in Boulder, namely with defensive coordinator Jim Leavitt and cornerbacks coach Charles Clark, plus increased interest from other Pac-12 schools has Osling taking a different position in his recruitment, choosing to back away from his committed status.
"My commitment to Colorado has changed," said Osling. "They're still in my top choices though."
One of the schools making a push for Osling is UCLA, which hosted him this past weekend.
"The trip was amazing," said Osling. "There is a lot more to UCLA looking at it from the inside out instead of the outside looking in."
Osling was hosted by defensive back Adarius Pickett.
"My host was Pick (Adarius Pickett) and he is probably one of the coolest dudes I ever met in my life," said Osling.
And when he wasn't with Pickett, he was with the Bruin coaches.
"I spent a good amount of time with all the defensive coaches and Coach (Jim) Mora," said Osling.
Growing up in Southern California, Osling knew that UCLA had much to offer, but the visit allowed for an up close look at it.
"What stood out most was probably how successful a person can be outside of football at UCLA and how much power having a degree from there holds," said Osling. "The campus is nice and pretty big. The facilities are nice and they're building a new football facility that should be done in June."
His teammate Moses Robinson-Carr committed to the Bruins on his visit and Osling said Robinson-Carr is already recruiting him for the Bruins.
"Moses has been texting me every two hours about college," said Osling.
Oregon State will host Osling next.
"I have an official visit to Oregon State on the 20th of January and that will be my last visit," said Osling.
UCLA and Oregon State are expected to have in-homes with him soon.
A final decision will come, publicly, on Signing Day.
"That school that I will commit to will know before the public and I will try to pull the hat on Signing Day if the school is ok with me doing that," said Osling.
