That's the BYU fan in you talking. As much of a trainwreck the Utah OC position has been, Utah is a PAC 12 school, they pay their assistants decent money, they're annual fixture in the College Football Playoff rankings, they have a great Poly recruiting pipeline, they recruit Cali extremely well for a team not named USC or UCLA, they recruit Texas better than they should be able to as well as Florida. If Whitt actually wants to step outside his comfort zone, go get a big name, and actually let him control the offense, he absolutely could.
My Dream candidate and a guy I 100% believe Utah could get is the Tuiasososopo kid out of UCLA. He's currently the passing game coordinator for the Bruins. Bringing him in as the OC is an immediate upgrade for him and a great chance to up his stock as a potential HC. The guy would be a slam dunk. He recruits the West as well as any coach out there and would only strengthen Utah's poly pipeline as well as allowing Utah to get some Cali kids they usually don't have a shot at.
Could Whitt make this happen? Absolutely. Will he? Absolutely not. If it's not Harding, it will be another unremarkable name out of Whitt's "lapdog" Rolodex.
