And Sanchez could be terrible but still win because our defense is so good.. just like the Woodley/Strock Dolphins went to a Super Bowl the year before.
It's a long season and there will probably be blowouts in one direction or the other - chances to get Lynch some experience and give the coaches a chance to see how ready/not ready he is to take over. If they believe Lynch gives them a better chance to win than Sanchez, the move might be made despite how the division title stacks up.
