"(Roberts) is ahead right now," Holgorsen said. "Keep in mind, we're in practice No. 4, not 24. He's ahead in terms of overall blocking schemes, protection and understanding where to go with the ball."
It's still anyone's position, Holgorsen admitted. He was impressed by other freshmen Dustin Garrison and Andrew Buie in Tuesday's practice. Holgorsen said Roberts "did some good things," as well. Holgorsen said Johnson also had strong moments in the practice.
"There is a level of competitiveness out there that is making those guys better," Holgorsen said. "It doesn't really matter that they're freshmen, because all of this is new."
Holgorsen considers Buie to be the running back with the biggest "twitch," which is something the offensive coaches look for in an "A" back. Garrison "makes people miss," Holgorsen said, better than any other back.
"Both of them are sharp kids. They have a bunch of football sense," he said.
Holgorsen would like to see three running backs in the rotation, but no more than three. That means that it's likely one of the four players in the running will be left out.
"He's doing really well … He's probably caught as many balls in pass skeleton as any guy we've got," Holgorsen said. "He's a pleasant surprise."
Holgorsen said that Brown will push for a starting spot at inside receiver. He and senior Tyler Urban are vying for that other starting spot on the inside alongside speedster Tavon Austin. The coach is also pleased with Notre Dame transfer Steve Paskorz at linebacker. He is playing middle linebacker behind starter Najee Goode.
Throughout camp, Holgorsen has tried to keep Smith grounded and not too confident heading into what some have called a Heisman campaign.
However, he told the team that those social media sites are being monitored and that the players are in charge of what others are posting on their Facebook walls.
"They're not allowed to talk about the other players or how practice is going," Holgorsen said. "If we catch them, we'll keep them after practice and remind them what our policy is." Holgorsen said being responsible with social media is part of maturing.
