With Buffalo playing most of their November Football on national television UB has had a chance to showcase the department and it's new direction. So far the on the field results have been mixed.
A big win over Ohio and a tough loss to Toledo got all the press but a logo change by ESPN did get a lot of attention.
In short ESPN isn't using the Bull logo anymore. During the Ohio game the score updates showed the white interlocking "UB" with blue outline rather than the Bull. Still for the next week or so ESPN.com was using the standard athletics logo.
Drilling down within game pages the Bull is still there but it looks like he is working his way out of ESPN's Buffalo related pages.
It's still "The Bull" on other media sites but ESPN is the organization who owns the media rights to UB games so branding changes that start there will likely end up other places.
