My first question is about the NFL challanging rule. I was watching monday night football like 10 minutes ago, and they said something like you can win a third challange if you win your second one. Is that true, and if it is, when did they put that rule in?

My next question is about Adrian Peterson. I know his injury this week wasn't career ending, but lets pretend it was. If Adrian Petersons injury was career ending, would he be considered the biggest mistery of all time. Would people say he could have been the best ever but got injured, kind of like Bo Jackson???

In order for a team to receive a 3rd challenge, they have to win both of their challenges. The team is then awarded a third challenge, as long as they have timeouts left in order to use it. The rule is brand new this season.

As far as Adrian Peterson, I think it is to early in his career for people to say he would have been the best ever. Bo played great for 4 seasons and put up amazing numbers as a back up to Marcus Allen. Peterson has only played 10 games, and 6 of his 8 touchdowns and 520 of his 1081 yards came in 2 games. He is to hot and cold to be considered the best of all time. Don't get me wrong, I love him as a player and think he will have a great career, but it is to early to whisper about best of all time.

I'm sure you would hear people saying that about Adrian...

1.Yes you can win. You get 2 chances (2 wrong challenges and your done with it) for challenges and you can only challenge if you have timeouts.
2.It's and if question but it's not. He'll likely be back in week 12. He could be great like Bo.

I don't think it will be the Greatest mystery in football or all time. But it would be something that came to mind every time you thought of the Vikings or him as a player in general. Especially his rookie year.
