The college basketball season is just over two weeks long, and we’ve already seen plenty of dramatic upsets. Opening night was stunning as UCF fans stormed the field after the Knights upset a ranked Texas A&M team while Arizona went on the road last week and lost to an unranked Wisconsin team.

Throughout the regular season, we’ll check in every Tuesday in this space to identify ranked college basketball teams that should be on alert for a potential upset. Without further ado, let’s begin our Week 3 upset alert guide with a look at why Purdue could be in trouble this week.

No. 6 Purdue

One of the most important games early in the college basketball season took place last Friday when Purdue hosted then-No. 2 Alabama and beat the Crimson Tide by nine. The result was impressive for Matt Painter’s new-look Boilermakers, who are trying to establish themselves as a national title contender despite losing Zach Edey to the NBA.

Trey Kaufman-Renn helped fill some of Edey’s vacancy and scored a career-high 26 points to help knock off Alabama. It’s worth noting that the Boilermakers shot over 50 percent from the perimeter in their win over the Crimson Tide, which overshadowed the fact that they had to fight tooth and nail to beat Yale at home earlier in the week.

Tuesday marks the first true road game of the season for Purdue, which heads to No. 15 Marquette, which already survived its own road test with a 78-74 victory over Maryland last week. The Golden Eagles retain most of the roster from a team that was the No. 2 seed in last year’s NCAA Tournament and are ready to make their first major statement with an upset against Purdue.

No. 8 Alabama

One of the things that makes Alabama’s Nate Oats such a good coach is that he’s not afraid to schedule tough competitions in the non-conference portion of the season. Oats believes playing against top foes sets his team up for success in the unique NCAA Tournament. So he’s willing to take a loss or two in November and December in order to better serve the bigger picture.

Alabama is coming off a loss at Purdue on Friday night and has another tough game ahead as it plays a (technically) neutral site game against No. 25 Illinois on Wednesday. The game will be played in Birmingham, so it’s a virtual home game for the Crimson Tide, but Illinois is one of the most underrated teams in the country.

The Fighting Illini have the kind of high-powered offense needed to get up and down the field with Alabama, giving them a strong chance of staying in the contest. When you factor in potential NBA talent like guard Kasparas Jacucionis, Illinois has everything it needs to hit the road and hand Oats a second straight loss if the Crimson Tide isn’t blocked.

No. 11 Tennessee

Rick Barnes had his work cut out for him in the offseason with Tennessee after losing a ton of experience from last year’s team, including first-round pick Dalton Knecht. The Vols did a good job reloading their roster and got off to a 4-0 start, although three of those games were buyout games against mid-majors and the fourth was a road date against Louisville, which is just beginning a rebuild after the disastrous Kenny Payne era.

This week, the Volunteers travel to the Bahamas for the Baha Mar Hoops Bahamas Championship, where their first game is Thursday against Virginia 3-0. While not a vintage Cavaliers team, interim head coach Ron Sanchez maintained the group’s signature Pack Line defense, which stifled foes to the point of allowing just 53 .7 points per game so far.

It takes a certain mentality and patience to succeed against the Pack Line, which Tennessee should have thanks to the leadership of senior guard Zakai Zeigler. This game could end up being tough, though, and if Tennessee presses too hard, they could become the Pack Line’s latest casualty on a neutral field.

No. 19 Wisconsin

There is no better example of how reactionary college basketball polling is than what happened in Wisconsin. Despite being picked 12th in the Big Ten preseason poll, the Badgers jumped into the Top 25 after an upset of Arizona at home, raising hopes that Wisconsin could be a factor in the one of the deepest conferences in the country.

The Badgers continued that effort by nearly missing a home game against UT Rio Grande Valley on Monday, winning by just three points as they improved to 5-0 on the year. However, all five of those wins came at home and Wisconsin finally leaves the comfortable confines of the Kohl Center to take on UCF in the Greenbrier Mountain Tip-Off event in West Virginia.

As we mentioned earlier, the Knights made a big mark early in the year with an upset over Texas A&M and have the talent to build on that effort with a win over the Badgers to improve their resume. Wisconsin will have to put in a much better effort than it showed Monday to win a neutral-site matchup with a dangerous power conference foe.
