I will say this is one thing that has always fascinated me about team sports. Compare soccer, which often ends in 0-0 or 1-1 ties (after regulation); hockey is pretty close to this too. For these games, one would think luck is a huge part. The other extreme is basketball, which may have close to 200 shots on each side with scores of 100 not uncommon. Football and baseball fall between these two extremes. I find it interesting that soccer, which probably has the greatest amount of "luck" (i.e., a single goal, a fraction of an inch that separates a save from a goal, is quite frequently the margin of victory) is also the sport associated with some of the most extreme celebrations and riots associated with the results.

I think the number of "levels" depends largely on how much variance we expect in performance from game to game, and how much the game counteracts that variance through "repeated measurement".
