Start off by begrudgingly talking about Donny boy and how he just can't stop talking about sports. Then we talk about CTE, the Tour Championship and the meaninglessness of streaks in baseball. For cricket and cycling, we touch on the significance of playing in Pakistan and a new UCI president. Our main topic for the week is what it means to be a world champion. When is it legitimate? Does it matter? Finally, we end of "I think" pieces on conferences and the baseball playoffs.
