"Only six practices in, I couldn't be more pleased," he said.
With returning back Kelvin York still bothered by turf toe, both backups Lucky Radley and James Poole had solid efforts.
Their success was keyed by an offensive line that Whittingham said is the most improved area of the team.
Backup quarterbacks Adam Schulz and Brandon Cox are keeping the pressure on starter Wilson, with Schulz in particular picking up the no-huddle offense well, Erickson said.

"The key is how you react, and we reacted well," he said. "Maybe a year or two ago we wouldn't have reacted like that. This is a fun group. I am excited. We are a lot better than people think we are."
Waiting game: The kicking game continues to be inconsistent with freshman Jamie Sutcliffe and Andy Phillips struggling. Whittingham said he was in no hurry to settle the position.
"We might not know until seven days out," he said about the season opener.
Sidelined: Utah's injury list is a long one with several key defenders out, including defensive end Nate Orchard (back) and linebacker/defensive end Jason Whittingham (shoulder), who had surgeries last week. Defensive end Trevor Reilly and Wykie Freeman already were scheduled to miss practice while recovering from injuries.
Linebackers V.J. Fehoko and Reshawn Hooker also are out.
"Half our starting defense is in the pit," Whittingham said.
Of note: Freshman Justin Thomas, who is competing with junior college transfer Davion Orphey for a starting role at corner, has moved ahead, Whittingham said. ... The Utes are scheduled to practice Tuesday from 3 to 5 p.m. ... Former Ute Luther Elliss spoke to the team after practice.
