This sets up the opportunity for incredible moments of redemption.

I love that onTANnobody goes home empty handed everyone gets a pay day winning with their team.

Why do you all tend to gravitate towards players with a little more experience?

What can you say about the challenges this season?

What’s great about going into a season 4 is that our audience alerts us to challenge ideas.

Any other new wrinkles this season?
