FiveThirtyEight ran the numbers after Kentucky's win on Friday afternoon. The result? Kentucky basically has a 1/3 chance to run the table undefeated.
"The Wildcats did enter the Final Four undefeated in about 66 percent of our simulations, but the biggest obstacles to their undefeated bid will likely await them in Indianapolis. Even if they make it to that point unscathed, their probability of joining the Hoosiers among the ranks of the unbeaten would be just a shade over 56 percent."
