The harsh reality is that amid everything the Utes do to memorialize him, they must be mindful that Uhatafe was driving the vehicle that crashed in New Mexico, killing Vaenuku and two other passengers: Uhatafe's 13-year-old brother, Andrew; and his stepbrother, Texas A&M defensive lineman Polo Manukainiu.
So whether the Utes keep Vaenuku's jersey hanging in his locker or wear No. 95 decals on their helmets, they also have to remember Uhatafe because he'll never forget what happened on the road from Utah to Texas.
Lives lost, lives radically altered. There's dying, and then there's living with it, as only Uhatafe can know.
"It's tough on him, he's been through a lot," said Utah coach Kyle Whittingham, who attended Vaenuku's funeral Saturday and met with Uhatafe's family in the Dallas-Fort Worth suburb of Euless, a Polynesian stronghold.
"We talked through a bunch of issues," Whittingham said. "By the time we left, he was pretty upbeat and understanding the bottom line, that [Vaenuku] would have wanted Salesi to move on and get back with his teammates, and that's the attitude he's taking."
It helps that community bonds and strong faith have enabled Vaenuku's family to forgive Uhatafe. Yet that's only part of the healing that must occur on so many levels.
Imagine what this is like for quarterback Micah Thomas or defensive lineman Sam Tevi, knowing they could have been riding in the SUV in New Mexico, if not for deciding to fly home to Texas during the short break between summer conditioning and the start of practice. They took the field Monday for the first time as college football players, missing a teammate and a fellow Trinity Trojan, in Tevi's case.
Knowing he recently rode around the Salt Lake Valley in Uhatafe's vehicle, the one shown mangled in all those photos, is "kind of a chilling feeling," Thomas said.
Thomas' tweets last week were even more poignant: "People don't understand how close you get and how fast you bond when each day you put your heart out there and work with one another." And "I was supposed to ride back to Texas with them."
Tevi knew Monday would have been like those old times in Euless. "He'd be right next to me, grinding," he said, walking off the Ute baseball field.
Which is what Uhatafe will be doing, once he reports next Monday, according to plans. The task of his teammates will be to "just make him feel comfortable, make him feel at home just the little things to keep a smile on his face," Tevi said.
That never would have been an issue with Uhatafe, until now. For the Utes, this is not quite like the 2005 death of former lineman Thomas Herrion, who collapsed and died during a game with the San Francisco 49ers. In this case, there's a survivor.
So as they honor the memory of a departed teammate, the Utes really need to support the one whose life goes on.
