I don't.
I kind of like Alabama, actually... although I seem to always root for Auburn when they meet each other - for reasons unknown to me.
BUT... just too successful, I want them to lose this year... but unless they play the Patriots for the Championship I don't see that happening... and when I say 'don't see it' I mean no chance in hell for anyone to knock them off.
Of the top five I would root most for Washington, (west coast)... then Clemson. I'm not a fan of either but those are the two I'd like to see win of the top 5 currently ranked teams.
In the top 25 the teams I like the most are Colorado and Stanford... and I would very much like to include Navy... being a Vet - BUT - I'm an Army Vet so if I rooted for Navy I'm pretty sure I'd be deported. - JamesJM
