What's this mass exodus from the offense of which you speak
? OJ is the only Sr., Cam will go early and maybe Foster if he has a great year and we don't know for sure if he will even start; the same for Deiter, who is a Sr. That's it. Possibly 9 returning starters, at least 8, as things now sit.
More importantly, why do you think Hurts makes more errors than CB and BB ? I have no inside info, nor do I attend practices, but by most indications, JH and CB seem similar in that regard, with both being better than BB. And Hurts doesn't seem to be run happy as opposed to Bateman who seems too reluctant. Hurts appears to be very mature with his decision making and not afraid of the moment. Having said all of that, who knows how any will react when the lights come on. I trust the coaches, but Hurts is exciting to anticipate, though some of that is because of the unknown.
