Homecoming: Northern Arizona @ UC Davis		Nava is still listed number one in depth chart at right guard
Rodriguez, who finished the game against Cal Poly, is listed behind Main at LG.  If I’m not mistaken Main played right guard at end of CP game in place of Nava, and according to game notes started in place of Rodriguez at left guard. Maybe they were trying to rest Rodriguez
If Nava is healthy then it seems they have everyone on the o line available. They still haven’t started a game with all the offensive lineman in the positions they started at last year, and probably won’t.
