Just 1,820 out of the 8.15 million brackets in ESPN's Tournament Challenge correctly picked Syracuse and Wichita State to reach the Final Four. Individually, 8.1 percent of brackets had Syracuse in the Final Four, while just 19,157 brackets (0.24 percent) had Wichita State reaching the Final Four.
Also, just 2,776 brackets have Wichita State winning it all (1.5 percent of all brackets have Syracuse winning the title).
Looking ahead to Sunday's games, the four teams playing are all reasonably popular picks to reach the Final Four:
Louisville (52.6 percent), Duke (23.4), Florida (20.4), Michigan (13.3)
However, despite all the popular picks playing Sunday, the number of brackets that will have an entire Final Four correct is going to be very low.
Potential Final Fours
Wichita State/Syracuse/Florida/Louisville: 53
Wichita State/Syracuse/Florida/Duke: 50
Wichita State/Syracuse/Michigan/Louisville: 47
Wichita State/Syracuse/Michigan/Duke: 47
