Texas A&M quarterback Johnny Manziel’s Pro Day threw the Twittersphere into a frenzy on Thursday, as fans, analysts and athletes rushed to evaluate the college star’s performance.

Manziel, who was considered to be one of the top quarterbacks in May’s 2014 NFL Draft, held his Pro Day on Thursday, working out for coaches and scouts from 30 of the 32 NFL teams, Yahoo Sports reports. The former Heisman Trophy winner completed 61 of 64 passes, taking every single snap from under center and delivering his throws with accuracy and power. “#JohnnyManzielProDay” quickly became a trending topic on Twitter.

“My main thing was, I am not scared of anything. I don’t play that way on the field,” Manziel told NFL Network after his Pro Day workout. “Why come out here in a scripted workout and be scared of anything? I just wanted to throw the pigskin around and have some fun.”

Johnny Football’s Pro Day contained a few notable caveats. First, the 21-year-old decided to wear a helmet and pads while throwing, something that most prospective NFL quarterbacks are unwilling to attempt. Furthermore, rather than simply sit back in an imaginary pocket and throw to his receiver, Manziel had George Whitfield, his personal quarterback coach, simulate a pass rush by chasing him around the field with a broom.

Manziel could also count a former U.S. president among his spectators. George H.W. Bush, the nation's 41st president, watched him throw from a golf cart on the sideline.

For NFL experts, Manziel’s ability to translate his unprecedented college football success into NFL stardom has been a source of endless debate. Several notable analysts, such as ESPN commentator Merril Hoge, have openly voiced their belief that Manziel won't be a successful NFL quarterback.

Manziel’s Pro Day reignited the debate over his draft status, as everyone from NBA forward LeBron James to Green Bay Packers quarterback Aaron Rodgers attempted to make sense of the young quarterback’s performance. Twitter reactions to the event can be viewed below, or by clicking here
