I don't see OG as a need at all.
Rhyan and Jenkins are under contract - that's it. Newman and Runyan are free agents and likely gone. Even if you re-sign one of them, they aren't good players. That means they have 2 guards on the roster. Very fair to say it's not a major need if you believe in Rhyan, but you can't go into the season with only 2 guards on the roster. You'd have to play musical chairs on the line with Zach Tom every time a guard gets nicked up.
