Most famous attendee of Johnny Manziel's pro day? Try a former president Will the former president make an appearance at Texas A&M on Thursday? Apparently, we'll just have to wait and see. Johnny Manziel won the Heisman Trophy following the 2012 season. Brian Spurlock / USA TODAY Sports By Ross Jones Mar 26, 2014 at 5:56p ET Johnny Manziel decided not to throw at the NFL Scouting Combine or Texas A&M’s pro day earlier this month in anticipation for his private workout set for Thursday. The Heisman Trophy winner will work out before a mass of NFL personnel, but he’ll also have some other special attendees. Texas governor Rick Perry and former President George W. Bush will be in attendance to take in college football’s most polarizing player’s pro day, according to Fort Worth Star-Telegram writer Charean Williams. While Manziel has been projected to go in the first round, his throwing style will be watched closely. Other notable quarterbacks such as Central Florida’s Blake Bortles and Louisville’s Teddy Bridgewater staged their pro days earlier this month.
