Some aren't big enough and if they are big enough they aren't mean enough.
"They all need to change their mentalities, which is a process, and we're doing it," Crook said. "We're doing it and we've come a long way in it. The running game has been improving as we go through the season and I hope we see it continue to improve.
"As far as there being a different type of body, that's what we want to do regardless. We want to get bigger and get stronger and maintain athleticism."
The Mountaineers are making changes while they're changing. Pat Eger is a senior who was made a starter because of his game experience, but he'd never started at center before getting the nod in the season's third game against Georgia State. He was a backup a week later and has been the starter since. Snaps still aren't guaranteed and even slight errors mess up the timing in the run and pass game.
Quinton Spain had been the starting left tackle, but he was moved to left guard two games ago. Spain is WVU's biggest and, in some opinions, best offensive lineman.
"One thing (Spain) can do inside that he wasn't able to do as well outside is come off the ball and go forward a little bit more," Crook said. "At tackle, a lot of the time you're on an island. I think this plays to his mentality and the things he can do physically a little bit more."
The line's most important spot now belongs to Nick Kindler. He's a serviceable player who's been good as a starter, but who had been a reserve his first three seasons. Those moves bumped sophomore Marquis Lucas to a backup spot at left and right guard.
"A lot of moving Spain was about giving us a chance to get more experienced guys on the field who have played more games for us," Crook said.
Whether it's the change in personnel or in philosophy, the Mountaineers need time to make use of so Crook has better things to talk about.
"Everyone has a tough time when you get beat like we did," he said. "It's not easy on anyone. It's not easy on anyone on the team, it's not easy on anyone on the staff, it's not easy on anyone in the program.
"You just come back and say, 'OK, you can't change it. It happened. It's done now. We've got to get to moving forward.' This team is going to be judged by how we move forward and not by how we did two weeks ago."
