Announcers and journalists should be objective. They can push the big ten agenda and be honest about both teams.
It is not mutually exclusive.
Two things, neither guy is a play by play guy by trade. Both are traditionally color guys so the play by play was awful and the legwork necessary to make it less so looks like it was barely done. Also these guys are not journalists, they're paid employees of the Big Ten. As such they are propagandists, kind of like home team baseball announcers on local coverage, or Jerry Jones' radio show hosts. With those two situations in play we got what I expected out of them after just a minute or two of watching.
