NCAA Tournament 2017: What to watch for Saturday with Final Four on the line

Police say the junior who averaged 18.5 ppg this season was in possession of about 30 grams of marijuana during a traffic stop in Indiana.

Half of the Final Four will be decided Saturday as two teams will punch their ticket to Phoenix.

We know at least one team will be making its first-ever trip to the Final Four because the winner between Xavier and Gonzaga will be playing in the national semifinal for the first time in school history.

Oregon has been to a Final Four, but not since 1939 when the Ducks won their lone national title. If they are going to end their championship drought, they'll have to knock off one of college basketball's blue-blood programs in Kansas.

Here's a look at Saturday's Elite Eight matchups:

No. 11 Xavier vs. No. 1 Gonzaga (6:09 p.m. ET on TBS)

The Musketeers (24-13) have not had an easy path to the Elite Eight, beating No. 6 Maryland, No. 3 Florida State and No. 2 Arizona. Now they get top-seeded Gonzaga (35-1), which boasts one of the most-balanced offenses in the nation.

The Bulldogs have five players averaging double figures, led by All-American Nigel Williams-Goss. The 6-3 junior guard is averaging16.5 points to go with 5.9 rebounds and 4.7 assists per game. He'll have his hands full with Xavier's Trevon Bluiett, who is averaging 25 points during the NCAA Tournament.

Xavier could join the 1986 LSU Tigers as the only teams to beat the top three seeds in its region since seeding began in 1979.

The Ducks (32-5) have a daunting task in trying to figure out how to slow down the juggernaut that's been the Kansas offense. The Jayhawks (31-4) have scored at least 90 points in each of their three tournament wins, including Thursday's 98-66 whipping of No. 4 Purdue. Before that it was a 100-62 thrashing of No. 16 UC Davis and then a 90-70 thumping of No. 9 Michigan State.

But with five players scoring better than 10 points per game, the Ducks do have the offensive firepower to keep up with Kansas. The question is whether Oregon has the defense to keep Kansas' dynamic trio of Frank Mason III, Josh Jackson and Devonte' Graham in check.
