As for expecting the unexpected, unforuantely besides maybe some stunts or something, there isn't enough teams to really mess with eliminations. And this late in the game, I honestly can not see them offing a team mid episode.
Now I would like to see them change the format of the final leg and instead of placing some of the tasks at another destintation thousands of miles away. I would much rather see them get to the lower 48 at the start and then have a full amount of roadblocks, detours and stunts at routemarkers giving a real chance for the team who races the best leg to actually win.
For example last season, I like Tyler & BJ. So I wasn't unhappy they won (and they did run a fairly strong race except for 3 legs). But they didn't run the best overall leg, and thats what bothers me. I don't care for that, and with how they set up final legs, it makes it so much easier for a time to just do one event the best (as long as its the final one) and for them to win.
Now I understand why they do this. It makes the ending more exciting.
But really, this isn't a leg to win a trip or jet skis or 20,000. This is the most important leg, the one that should reward teh best racers, or at the very worst the team that runs the best final leg.
