Playing in the NFL can sometimes give a man a giant ego, or give him a serious reality check - you decide which one Johnny Manziel falls into.
It demands the attention and focus from not only a global fan base, but all players of the other 31 teams in the league.

Charles can often be considered one of the top runningbacks in the league right now and there may even be some who claim that with a better offense around him, he could help lead a team to the Super Bowl.
With Charles being the focal point of the Chiefs offense, this tends to lead to opposing defenses making a game plan centred on him.
Well now all the focus on him has given the runningback a great sense of self worth and he clearly understands that people are paying close attention to him.
"As long as I play in this league and play on a high level, I always feel like a team is going to have to stop me. I feel like sometimes I'm the LeBron of football, especially at my position because I can do so much." - Charles on his status in football
LeBron James of the Cleveland Cavaliers is one of the most influential men in basketball and one of the biggest sports stars in the world.
Comparing yourself to LeBron is no small matter so Charles is certainly making a big claim referring to himself as the LeBron of football.
Charles was responsible for 27% of the Chiefs yards gained last season so he is instrumental in his team's success.
Maybe he is right though, the team do rely upon the scoring efforts of Charles a lot more than they should sometimes - but maybe that's down to their wide receivers not scoring any touchdowns last season.
The Chiefs had a fairly awful year receiving wise last year with their receivers failing to catch a touchdown pass and the team missing out on the play-offs.
However with the arrival of wide receiver Jeremy Maclin in free agency, could they be set to change that?
Maclin had a good year with the Philadelphia Eagles last year and if he can be as effective for quarterback Alex Smith in Kansas, who knows how high the Chiefs can rise?
