"I came here as a fat boy and I'm leaving as a young man," Weaver said in his post. "... I poured my heart and soul into Boise State Football every time I set foot onto the field. I am forever grateful and honored to be a Bronco."
Weaver had 52 tackles, an interception and a forced fumble this season as the Broncos advanced to the Mitsubishi Motors Las Vegas Bowl, where they lost to Washington.
