"As we go on, especially in live situations, we'll learn a lot more about them and about how they can actually do it.''
There is also the issue of reacting to pressure, which can't be simulated in a closed workout.
"All four of them have the ability to make some things happen, but you've got to get them in a live situation,'' Holgorsen said. "You've got to see how they can handle the crowd and handle the live bullets and all that stuff. If he looks good then we've got to get him into the game.''
So, is there a pecking order?
"No, not yet. It depends on how they practice today,'' Holgorsen said before practice on Thursday. "It can change on a daily basis, right?''
When camp opened, Roberts was listed first on the depth chart with Johnson second and the two freshmen, Buie and Garrison, waiting to make their mark. When last he was willing to venture a guess as to the order, about a week ago, Holgorsen listed Buie, then Garrison and then Roberts.
But even Holgorsen isn't sure where they stand now.
"I ask Robert [Gillespie, the team's running backs coach] every day to give me his pecking order and it changes every day,'' Holgorsen said. "He's the one who's getting paid to be the running backs coach, so if his opinion changes, so does mine.''
