Re: go bulldogs!
In the US, virtually every college and university has a mascot/team name.
I didn't even need to read the part in your post that told me he went to Georgia -- I knew that when I saw the title of your post.
If I read "Go Wolverines" I'd know it was Michigan. "Go Buckeyes" means you are cheering for the University of Ohio.
Some are more fierce sounding than others. Sadly, my own university was "the Engineers." Nothing is quite so rousing as shouting "Let's go, Engineers." I wondered if the other teams thought we would throw our calculators and slide rules at them.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
