Three keys

3-POINTERS:

Kansas has scored 90 or more points in each of its three tournament games — the first team to do so in 22 years — by hitting 46.6 percent of its 3-pointers. That would seem unsustainable if not for the fact the Jayhawks have been doing it all season. Led by Frank Mason III (48.2 percent), Kansas hit 41.1 percent of its 3-pointers this season, ranking fourth in the nation. Oregon, though, has one of the best perimeter defenses in the country, seamlessly switching looks and limiting space with its athleticism.

EXPLOSIVE X-FACTOR:

Kansas’ Josh Jackson and Oregon’s Tyler Dorsey (right) are the biggest reasons each team’s ceiling is so high. Jackson and Dorsey, who may end up going head-to-head — both used as fours in small lineups — have been at their best on the biggest stage. Jackson, a freshman expected to be a top-three pick in the upcoming NBA draft, has averaged 18.3 points, 7.3 rebounds, 2.3 steals and 1.3 blocks in the tournament. Dorsey has scored 20 or more points in six straight games and has been the Ducks’ leading scorer in every game of the tournament, hitting 11-of16 3-pointers.

THE “NEUTRAL” SITE:

With the Sprint Center located a little more than 40 miles from Kansas’ campus in Lawrence, the Jayhawks have one of the most advantageous conditions the tournament ever could allow. In Thursday’s regional semifinal, Kansas fans snatched up virtually every seat not specifically allotted to another school. The support will be even more lopsided Saturday with Michigan and Purdue no longer around.
