I decided to take a look at stats from the 2010 D1 and D2 tournaments in terms of higher seeds advancing to see how they compare to what we are seeing right now. In this I consider upsets in round 1 a lower seeded team beating a higher one, and in round 2 whether a team advanced with a seed that shouldn't be in a sweet 16 (basically any seed 5-16). I actually thought the D2 Smith upsets seemed really abnormal but in RL there is much more parity actually. In the first round of the D2 tourney 37% of games had upsets. In round 2 - 62% had upsets - and only once did the top four seeds in a bracket advance to the third round. Smith D2 this post-season there were 43% upsets in round 1 and 75% in round 2. Both are higher than RL this past season. I personally think 75% is way too high but after seeing 62% in RL it's a little easier to swallow.
In D1 this past year, there were 31% upsets in round 1 and 50% upsets in round 2. In Phelan this post-season (where TWO #1 seeds lost to 16 seeds) there was 34% upsets in round 1 and a staggering 81% in round 2.
This last one stands out most. Nowhere near realistic. The sweet 16 consists of:
1,2,6,13
3,5,8,10
7,8,11,13
5,7,8,11
In all only 3 teams seeded 1-4 made the sweet 16. Expand to look at teams seeded 1-6 advancing and in the 2010 tourney 75% of sweet 16 teams were seeded 1-6. In Phelan, only 37% of sweet 16 teams were seeded 1-6.
Just something to chew on.
