If Otah comes back and expectations are that he will, Bell moves inside and we have a ton of beef on the right side. Hangartner takes over Wharton's place and it is all good. We have depth as well. No need for an OG or OT until next year at the earliest. Even if Otah struggles Bell will be improved at tackle and we have other guys who can compete for the guard position.
I think Otah will be fine.
