The top three running backs, the only ones being used now, are also newcomers - Sims, Dreamius Smith and Wendell Smallwood.
The quarterback, Clint Trickett, arrived as a transfer in June.
All are beginning to improve. Holgorsen said Trickett's fourth quarter in last week's overtime win at TCU was his best quarter of the season. Sims had more rushing yards, 154, than any player ever against a Gary Patterson-coached TCU defense.
And the receivers are coming.
"Mario Alford made three huge catches last week. He's going to get better and better every single week,'' Holgorsen said. "Daikiel Shorts had another big day. He's going to get better. Kevin White didn't perform, but he was being covered by an All-American corner [TCU's Jason Verrett] who's really good.
"So these guys are developing and they're going to continue to get better.''
Again, the evidence seems to indicate they already are. Sims, in particular, could be a huge asset down the stretch. But that still hasn't served to elevate the offense to the level at which it needs to be in order to compete every week.
And Holgorsen, who was asked if the performance at TCU allayed his concerns about his offense, knows that.
"Oh, absolutely not,'' Holgorsen said. "It's still a work in progress.''
Against Texas, West Virginia will play perhaps the most physically talented group of defenders it will see all season. It's a group that struggled mightily to start the season, but has settled in under coordinator Greg Robinson, who was brought on board as an emergency replacement after three weeks.
To have a chance against the Longhorns, West Virginia's offense will have continue to show that improvement.
"I do feel like we've constantly been improving and I do think we improved last week and I expect our guys to work hard and improve this week,'' Holgorsen said. "But there are also some things that exist with us offensively that are not going to get fixed until we probably have six months of offseason on our hands to be able to fix it. There's just a lot of new parts to our offense. And it's going to take some time for the continuity to improve to get to the point where I feel like it's winning football.''
