One thing that drives me nuts is the NFL rule that the coach can only challenge two calls.

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.

If they win them both they get another one, but I think the limit is 3. I'm not sure the exact limit but they do get a third if they win the first 2.
