One of the best days on the sports calendar is almost here: Shortly after 6 p.m. ET on Selection Sunday, we'll know which teams are in and which are out of the men's 2025 NCAA tournament field -- then we can officially start filling out brackets.
But ... not quite yet.
The selection committee still faces questions.
Should the Mountain West get as many as five bids? Did Champ Week impact the 1-seed debate? The crowded SEC and Big Ten contingent also bring plenty of bracketing wrinkles.
Here are the 10 biggest questions the committee will have to sort through, from the top of the bracket to the cut line.
