Arizona vs. Wisconsin: 3 things you need to know

Saturday's contest between Arizona and Wisconsin feels like deja vu.

Some things are different, but the teams meeting in the Elite Eight is a rematch of the 2014 West Region finals, which came down to a final possession in overtime. The No. 2 Badgers came away victorious, 64-63, over the No. 1 Wildcats.

Now, Wisconsin sits as the top seed of the West region, while second-ranked Arizona looks to get revenge and make its first Final Four since 2001.

Here are three things you need to know:

Both teams can blow opponents out 

Arizona has the third-best point differential in the nation, beating opponents by an average of 17.6 points while allowing its foes to shoot just 39.5 percent from the field. 

The Wildcats get great defense from their wing players, namely Stanley Johnson and Rondae Hollis-Jefferson, who sport steal percentages of 2.7 and 2.6, respectively.

Hollis-Jefferson is also an elite shot-blocker, swatting 3.4 percent of his opponent's two-point attempts. In comparison, Giannis Antetokounmpo of the Milwaukee Bucks, the "Greek Freak," blocks three percent of opposing twos.

Wisconsin's efficiency is nearly unparalleled, with a 15.2 point differential, good for sixth nationally and the second-best assist turnover ratio at 1.73.

Guard Bronson Koenig, along with forwards Nigel Hayes and Frank Kaminsky, have shown an ability to consistently locate open shooters, guiding the team to a 48 percent field goal percentage.

On defense, the Badgers make teams earn their points, allowing just 57.2 per game, good for 10th in the country. 

Sam Dekker has been on fire

Wisconsin forward Sam Dekker has stood out in the tournament.

The 6-foot-9, 220-pound junior, who averaged 13.5 points, 5.5 rebounds and 0.5 blocks, has turned up the heat in March Madness.

He's averaging 20 points, 5.7 rebounds and a block in three tournament games. 

Dekker was special in the Badgers' 79-72 win over North Carolina in the Sweet Sixteen, scoring 23 points with 10 boards.

Brandon Ashley could be trouble for Wisconsin

Brandon Ashley is someone to look out for Saturday. 

The 6-foot-9 forward, named MVP of the Pac-12 tournament, is second on the team in scoring, netting 12.1 points and 5.2 rebounds. 

He's been quiet in the tourney, but averaged 19 points on 70.4 percent shooting with 6.8 rebounds and a block in the team's final five games heading in. 

Ashley, who makes the most of his impressive 7-foot-2 wingspan, is averaging 9.7 points in three tournmanet games, shooting 46 percent from the field.

Ashley will be counted on to defend Frank Kaminsky, and his defensive range is apparent in his 3.3 block percentage and 1.0 steal percentage. 

If there's one hole in Wisconsin's defense, it's the ability for teams to get busy inside. Opponents have shot 42.3 percent against the Badgers, so look for Ashley to exploit the paint.
