To say the season is over because Gurley can't play against Missouri is an overreaction. (Understandable, but still an overreaction.) Chubb is a good player. Georgia was supposed to have a lot of good players, though the other Bulldogs have spent the first five games in the shadow of their shining star.
I remember a night at Auburn in 1986. James Jackson, Georgia's No. 1 quarterback, didn't show, having been delayed at a funeral, and the Bulldogs weren't supposed to beat Auburn in the first place. They upset the Tigers on the field, and not just on the field: Auburn officials were so ticked at the Georgia celebration that they turned water cannon on Georgia fans to make them leave. (The famous "Between The Hoses" game.)
Granted, Todd Gurley means more to Georgia in 2014 than James Jackson did in 1986. Todd Gurley is the best collegiate player in the land. But he's one player, albeit a splendid one, and it's time for the other guys on scholarship to show they can play a little, too.
