Backup Cs Collin Baxter and David Molk (round seven, 228th overall pick) have struggled with clean snaps to QB Charlie Whitehurst. Usually, it wouldn't be a major concern considering it's early June and they're learning to work with Whitehurst. But the Chargers will likely only carry one other C besides starter Nick Hardwick, making every snap count for the duo who will be fighting for a roster spot in training camp.
