I think not, while it puts the team in a great position for a 3 seed, most of the 3-5 seeds are still alive and good pushes deep into conference tourneys could be enough to push ISU down to a 4. 3 seed is fairly likely at this point but not assured imo.
ISU, Maryland, Notre Dame, OU, Baylor are the 5 teams probably still in contention for the 3 seeds.
Baylor needs to beat KU for a 3, I think ISU and OU are 3's unless Baylor wins tomorrow.
I don't why Notre Dame should be a three seed.ISU, Maryland, Notre Dame, OU, Baylor are the 5 teams probably still in contention for the 3 seeds.
