Head coach Chip Kelly said right now, it's up in the air.
"It's not different than any other position," Kelly said. "I understand more scrutiny is made on the quarterback position than anything else. Every day we come off the practice field, [the media] wants to know, 'How did the quarterbacks do?' No one was like, 'How did the gunner on the punt team do?' "
During organized team activities in the spring, Vick and Foles split first-team duties and Barkley worked with the third team, USA Today reported.
Kelly said it should become obvious at some point who should get the nod.
"Everywhere I've been, it has played itself out on the field," Kelly said. "Does that mean it's going to happen here? I don't know. But I've never been in a situation where we've had to make a decision and it was like, 50-50, pick it out of a hat.
"Somebody over the course of time has stepped up and won the battle. That's what you're hoping to have happen again here. Hopefully, it's evident to everybody, like, 'There's no question that it's this guy because his game stepped up.' "
