Code:
id    int(10) auto_increment primary key
team_id  int(10)
year    varchar(4)
team   ???
mascot  ???
sport   int(11)
state   int(11)
conference    ???
classification  ???

I have these questions:

#1 - Should team be an integer linking it to a team table or just put the team name within it.

#2 - The same question as number one, but pertains to mascot table.

#3 - Conference would most likely be something similiar "East", "Central", etc. Would it just be best to put that in it, or make a table and put the descriptions in, linking them with a foreign key

#4 - Same as the above, but would hold information akin to "AAAAA" or "AA", etc..

Which would be faster and more friendly when trying to extract data/compare things?

The thing is that each team would have to have conference and classification put together too, like: AAAA East, AA Southwest Things of that nature
