But when he was asked to try center after spring ball, Sibiea wasn't so sure.
Now, 15 days into fall camp it appears the Miami native will win the nod as the quarterback - the center - of the offensive line for the Cardinals in the coming season.
"I was surprised when they asked me to move," Sibiea said. "But I would do anything for the team."
The 6-foot-3, 300-pound SIbiea hasn't been named a starter just yet - line coach Chris Klenakis said 10 or 11 guys are battling for the five spots - bur coach Bobby Petrino raved about his new center after a scrimmage last weekend.
Senior lineman Aaron Epps said Sibiea is "taking advantage of his opportunity."
But that's no shock. Sibiea, the first U of L football player to ever study abroad when he spent time last spring in Panama, has always been an athletic lineman who seemed to put the team first.
Sibiea came to U of L as a defensive lineman but was then switched to offense by the previous staff only to move back to defense. And then last year he went back to offense as a backup guard.
He played guard all spring and was set to start at that position.
"It's whatever the coaches want," he said. "Now, I just look at the defense, picture how his stance is different, little tendencies that defensive linemen do, and if I was a D lineman, how would I adjust to it."
Klenakis said he feels like Sibiea is up for the challenge.
"Pedro has stepped in and picked it up," he said. "The biggest challenge for him now is that now he has to make the calls instead of listening to the calls. But he's getting there."
