Johnny Manziel tweets he's unhappy playing college football

Johnny Manziel might be the first freshman to win a Heisman Trophy in the history of college football, but that doesn't mean he's too happy with the way things are panning out.

The 20-year-old quarterback who has been dubbed "Johnny Football" for his impressive moves on the field wrote an unhappy post on Twitter early Sunday morning.

Deadspin

Manziel, a sophomore at Texas A&M University, deleted the post shortly after writing it, but followed up with a related tweet.

"Don't ever forget that I love A$M with all of my heart, but please please walk a day in my shoes," he wrote.

According to ESPN, Manziel's popularity has risen considerably ever since he won the Heisman Trophy in December. Kevin Sumlin, Texas A&M coach, said he's never witnessed a player getting so much attention.

"I've seen it, just like everybody else," Sumlin said. "I think being around other guys in the past has helped me, but there's never been anything like this before. Being around Adrian Peterson or Jason White or Sam Bradford or Case Keenum or Drew Brees, people like that, that's part of the deal. When you are a nationally recognized person, whether you're young or a freshman or an older guy, there are some things that come with that. "
