Thanks to some major upsets this weekend that wiped out a 1-seed and two 2-seeds, just 14 of the more than 11.57 million Tournament Challenge brackets got the entire Sweet 16 correct. Another 482 brackets got 15 of 16 right.

Here is a recap of Sunday's upsets and how it affected the brackets:

7-seed Michigan State over 2-seed Virginia

-- 27.1 percent of brackets had the Spartans in the Sweet 16 (most among 7-seeds); another 9.1 percent have them in the Final Four, surprisingly high for a 7-seed. Then again, the Spartans were the most popular Final Four pick in their region last year despite being a 4-seed.

-- Virginia was picked to reach the Sweet 16 in just 68.2 percent of brackets but was picked in 32.6 percent of brackets to reach the Final Four (fifth-most popular overall and tops in the East region), 15 percent to reach the title game (third-most) and 3.4 percent to win it all (sixth-most)

-- Michigan State draws Oklahoma next. 18.7 percent of brackets picked that particular matchup, with 65.4 percent of those brackets taking the Spartans.

7-seed Wichita State over 2-seed Kansas

-- 26.9 percent of brackets had the Shockers in the Sweet 16, but just 1.3 percent have them in the Final Four

-- Kansas was picked to reach the Sweet 16 in just 65.7 percent of brackets and the Final Four 5.4 percent of brackets (both lowest among 2-seeds)

-- Wichita State draws Notre Dame next. 21.4 percent of brackets picked that particular matchup, with 25.7 percent of brackets taking the Shockers to the Elite Eight.

5-seed West Virginia over 4-seed Maryland

-- 27.3 percent of brackets had the Mountaineers in the Sweet 16, but just 0.7 percent have them in the Final Four.

-- 31.6 percent of brackets had picked West Virginia to lose to 12-seed Buffalo in the round of 64.
