Most players who are good enough to play in nfl, were star players in college and high school.
So they have been spoiled,pampered, glorified,get whatever they want, teachers make it easy for them, and any wrong doings
are smoothed over , and taken care of, to keep them on the field.
This leads to problems once they hit the nfl.
Some may have smoked weed since HS, and like some here, they think it is ok and rules are stupid.
They have never worked a real job, and they really dont see clearly what waits for them if they blow their nfl career.
So they either think they can beat the tests, but then dont, or they think somehow it will get smoothed out as in the past.
Surely they wont get cut because they are so good.
Then add to that , they get paid while on suspension ?? I think they do, and to me that just makes some think why not?
Also many of these guys are just not too bright.
Another thing is to many of these guys the money they get initially, is a lot of money to them, so they think it will last a long time
and they have no idea how quick it will go, and probably give no thought to what they will do if they get phased out of nfl.
And some might think it is ok to get cut from a team, and then they can straighten up and get with another team.
But it all goes back to the life they have led for the 8 years or so leading up to the nfl and how they were treated and taken care of,
