SAN ANTONIO (AP) A wave of positionless basketball has swept the nation. Coaches have loaded rosters with smaller, athletic players who shoot 3-pointers and beat defenders off the dribble. Three, sometimes four-guard lineups have become the norm, free-flowing the way to go.

This year's Final Four teams certainly fit the mold. These final four also have something else in common: Skilled big men who keep defenses honest, grab rebounds and protect the rim with all those smaller guys out there.

Villanova has Omari Spellman, Kansas Udoka Azubuike. Moe Wagner is Michigan's man in the middle and burly freshman Cameron Krutwig anchors the paint for Loyola-Chicago.
