The Cardinals lost tackle Travis Leffew and guard Jason Spitz, both expected to be National Football League draft selections, and tackle Jeremy Darveau. Louisville does get back Renardo Foster, a two-year starter who spent last season recovering from injury. On the other side, sophomore George Bussy and junior Marcel Benson appear the leading candidates to replace Spitz and Leffew.
So what does Bush think about his new blockers?
"So far, so good," he said. "They've still got to work some kinks out, but right now I think they're doing a good job."
Bush said the offensive linemen have worked hard to prepare for spring drills, and will spend the next few weeks trying to perfect their assignments and techniques.
"They're working hard, and studying their book real hard," Bush said. "If they make a mistake, it will be a small one. Everybody's allowed to make one mistake, but in this offense you really have to be perfect. Everybody is doing a good job trying to get their assignments down. We're just out here competing. They'll be OK."
Bush and his teammates were also excited to put the pads back on Saturday morning, even though there was no live tackling during the two and half hour practice.
"I think a lot of guys were excited about it because all winter we've just been lifting weights," Bush said. "I think (we) enjoyed it."
Bush also said he's feeling much after being slowed late in the season by an injury to his right foot. Though he still experiences some pain, it doesn't appear Bush will be slowed by his foot this spring.
"I just have a little soreness after practice," Bush said. "That's the only thing that's bothering me."
