Why Don't We Claim all our Football Championships?

it seems like the status quo these days is to count any and every championship in college football, regardless of what poll names the champion. Alabama, ole Miss, and Tennessee come to mind. If you go to college football warehouse, by those teams' systems, we can claim 1908, 1934, 1935, 1958, 1961, 2003, and 2007. That gives us 7. I just hate it when people say Tennesee has 6 when they really only have two or when they say ole Miss when they really have 0. I mean it would just sound so much better to a recruit or just our national perception if we claimed all ours like everyone else does.
