The NBA and NFL will introduce a new policy that states that athletes can not use social networks such as Tweeter, Facebook, e.t.c before, during, and after a game.

A: I think that it's not relevant to revoke the athlete's priveledges from using social networks before games. But with every bad thing, there's a good. Now that athletes can't use social networks nobody will know what the athletes are up to. You know people now of days, obsessed fans stalk famous celebrities.
This is for the athlete's safety.
