Brennan Randall Marion (born August 25, 1987) is an American football coach and former player who is currently the offensive coordinator for the UNLV Rebels. He was signed by the Miami Dolphins as an undrafted free agent in 2009, but never played in an official game. He played college football for the Foothill Owls, the De Anza Mountain Lions and the Tulsa Golden Hurricane, where he set the single season NCAA FBS yards-per-catch record in a single season at 31.9, and finished as the NCAA career leader at 28.7 yards-per-catch. He had back-to-back 1,000-yard receiving seasons. After playing four seasons of college football at three different schools, Marion was eligible to be selected in the 2009 NFL draft, but went undrafted.
