By need and design, the coaching staff has incorporated a long list of players to see who can do what.
Final evaluations will wait until after the spring and probably even into camp in August, but they'll begin to look a little closer as they near the Gold Blue Game April 29.
"The latter part of this week and next week we'll probably cut it down a little bit, but we need to find not only ones (first-team players), but you want to find guys who provide depth," said Casteel, the linebacker's coach. "When we're good, we're a good two deep and in some places three deep.
"At linebacker, we've got to find five, six guys who can come in and play and have a chance to be pretty good. I think we have an idea who we can start out with, but we're trying to find some guys that can play and be a 10- or a 15-snap guy for us."
Holgorsen won't narrow his focus as much and wants to use the final five practices the same as he used the first 10 so WVU can get as much from as many people on film as is possible. That means keeping the nearly even split at quarterback between junior Geno Smith and freshman Paul Millard.
"You need a backup quarterback," said Holgorsen, the quarterbacks coach. "Because Paul is so inexperienced, we believe the best thing right now is to have a 50-50 split. As we get closer to game time and even camp, we'll start giving the starter more, which right now would be Geno."
Players have started to establish themselves. Casteel knew what he had in senior defensive lineman Julian Miller and was optimistic defensive end Bruce Irvin could be as good as he has looked. Linebacker Najee Goode, cornerback Keith Tandy and safety Terence Garvin had also made their names in the past. Yet Casteel named presumed nose guard Jorge Wright, linebacker and junior college transfer Josh Francis and freshman cornerback Avery Williams as players who have earned his attention.
"I don't know that anybody's been a great surprise," Casteel said. "We still have a lot of guys out there learning and learning to compete every day, but we have had some kids who have played well."
Tyler Urban, a former tight end who has transitioned to slot receiver, has been one of WVU's best players on offense. Holgorsen said he's identified his best four receivers.
When Brad Starks was lost last week for three months after shoulder surgery, Holgorsen moved Stedman Bailey from slot to outside.
"He and Tyler were playing the same spot," Holgorsen said. "In our opinion as a coaching staff, they were two of our top four guys."
The other two would be Tavon Austin inside and Ivan McCartney outside. Running back hasn't been as illuminating and freshman Vernard Roberts came on strong the past week and took a lot of the snaps Shawne Alston vacated when he sat out Monday. Alston is day-to-day with a neck strain, but neither he nor anyone else on offense is working on a deadline this spring.
"We're all about doing what we've got to do to piece together the next practice," Holgorsen said. "We feel like the best thing to do is to put guys in position out there so they can continue to get evaluated. More than likely things are going to change over the course of the next six months."
