Doesn't have to be the best player. Just personally, somebody is going to be "your guy" no matter what.
For me, it's a split between two players. I was at Virginia Tech from 2006 to 2011 and Eddie Royal was my favorite player when I was in college. I thought he represented BeamerBall through and through. One of the best special teams players in the history of Virginia Tech. Personally, he's my #1 WR in VT history in terms of raw talent. Comes from an awesome family with his older brother playing at Marshall and currently, the CB coach at Morehead State. His younger sister is a VTCC alum and currently serves with the USAF. In addition, I thought he was a fantastic ambassdor post-4/16 and continues to represent Virginia Tech exceedingly well.
The second guy for me was Chuck Clark. I honestly think he's one of the most underrated defensive players in the Bud Foster era. Sam Rogers said he's the only person who matched his work ethic in college. Grinded from being an unheralded high school recruit to sixth-round nobody to making over 10 million in the league. Epitomizes the lunch-pail mentality. I still don't think he gets enough credit. BAMF.
