What is a seed?
A seed is a team's regional rank.
Seed 1 is strongest.
Seed 16 is weakest.
First games pair high against low.
What we don't do
The picker opens on Selection Sunday, March 14, 2027. Brackets start then.
We don't host pools, take entries, or handle prize money: you print or share your bracket and run your own pool.
Your five answers do the picking: your favorite, your upsets, your calls. Not a rankings or stats model.
