One of the most craziest injustices in our society has to be the NFL rule that the coach can only challenge two calls on video replay. The coach should have two chances to be wrong - but if the coach is right both times, why should he be limited to being right only twice? Why penalize a team because the coach was right, after two bad calls? So long as the refs are making bad calls, the coaches should have the right to set things straight. Of course, if the coaches start abusing this right by challenging calls which were good, they should be cut off. Please call, write or email your local NFL franchise to complain about this rule.
