You have no idea if he makes picks out of personal bias. He doesn't hide his bias, not does Tebow whom has picked for and against Tennessee. I wouldn't want them to hide it. I'm sure he doesn't like Tennessee, nor should he. He can not like Tennessee yet pick against them because he thinks Ohio State will win, which isn't some audacious take. He has picked UT to win before as has McElroy.
Where is your outrage about Ron Slay picking against UT rivals in bball? Does that bother you? Is he unprofessional when he makes videos trolling the schools in the SEC? You're not guilty of selective outrage are you? Surely Slay bothers you as well?
We are talking about picking football games, here. This isn't life and death stuff.
