Here's a look at Day Four from Texas Tech fall football camp ...
* The Red Raiders gave a more spirited effort than they did on Wednesday, when coach Tommy Tuberville lamented the team's lack of energy.
"Much better today," Tuberville said. "A lot of enthusiasm. It's even hotter today than it was yesterday, but we executed well on the offensive side of the ball. They're starting to make a few plays, get the timing down, shaking the rust off a little bit."
For the first time since camp started, there were a few bouts of pushing and shoving -- nothing serious, but enough to get players from both sides more engaged in the action.
"That's going to happen," Tuberville said. "You're going to have guys go over the top a little bit when he thinks the other guy is doing something he shouldn't be, but it's competition and trying to earn positions. We didn't have much of that the last couple years."
Tech will suit up in full pads for the first time on Friday, but Tuberville said there will be less contact than players had on Wednesday and Thursday. Friday's session, he said, will be a light one as the team works on assignments and prepares for the first scrimmage of camp at 5 p.m. Saturday.
* Players seem to be buying in to the end-of-practice, strength-and-conditioning exercises. At one station, players work on foot speed by quickly stepping up and down a block of turf; at two others they slam medicine balls into the turf over and over in short bursts; at others they pull rope attached to a weight or push a sled.
* Bradley Marquez missed his second straight day of workouts with the flu, but LaAdrian Waddle and Deveric Gallington returned after missing Wednesday's session.
*Offensive line coach Chris Thomsen said Thursday's practice was the best from his unit.
"I thought our guys really competed today, this fourth day," he said. "We really challenged them and they came out and accepted that and did a good job. The leadership stepped up and the younger guys really rose up and followed."
Thomsen said Waddle and Gallington had temperatures over 100 degrees Wednesday and "really showed a lot of character, a lot of leadership, coming out here. They stepped up, the younger guys followed and we had a better day."
Thomsen pointed to Alfredo and Tony Morales, Le'Raven Clark and Beau Carpenter as young players who have stepped up early in camp.
"Those guys right now kind of stand out," he said.
* There will be no media availability following practice Friday, but media day is Saturday morning, so stick to the blog for plenty from that event.
