AUSTIN, Texas (AP) – Baylor quarterback Robert Griffin III has one last chance to impress Heisman Trophy voters.  Griffin and the No. 19 Bears (8-3, 5-3 Big 12) host Texas on Saturday. Another big game against the Big 12’s best defense could persuade undecided Heisman voters he’s the best player in the country.  Baylor fans will be wondering if this will be Griffin’s last game in Waco. The junior says he hasn’t decided whether he’ll return next season or leave for the NFL. Griffin already has earned his degree in political science.  Texas hopes to knock Griffin out of the Heisman race instead of trying to help him win it.  The Bears will be playing for their first nine-win season since 1986. Texas (7-4, 4-4) is trying to avoid a second-consecutive season with a losing conference record.
