Watch: Deja 'Boo' for Purdue as Buie leads Northwestern to upset

After losing 11 straight matchups with Purdue heading into last season's upset, Wildcats head coach Chris Collins has Northwestern on its first winning streak against Matt Painter's squad since 2013-14. It's also just the seventh time since 2010-11 that a team has taken down the AP No. 1 team in consecutive seasons. 

"We came in and knew exactly what we wanted to do," Buie told Andy Katz after the win. 

"It came down to the coaches harping on us all week, they did a really good job preparing us. We knew it wasn't going to be easy, we just gave it everything we had and came away with a win."

Purdue (7-1, 0-1 Big Ten) is the second No. 1 team to fall this season after then-No. 4 Marquette knocked off Kansas at the Maui Invitational. It's also Northwestern's (6-1, 1-0 BIG Ten) first top-25 win of the young season — it won't be their last. 

The Wildcats won 23 games last year en route to a third-place Big Ten finish in 2022 and a second-ever appearance in the NCAA Tournament. Collins' roster also has the increasingly rare advantage of four returning players from last season in his starting lineup; with Buie playing his fifth season in Evanston and fellow senior Ty Berry adding 21 points of his own in the latest win over Purdue.  

It looks like Collins has taken advantage of the transfer portal as well with the addition of Ryan Langborg, who garnered national attention during Princeton's Cinderella run to the Sweet Sixteen last year and hit four three-pointers vs. Purdue. 

Northwestern is a team with experience beating good teams both in the regular and post-season, so don't be surprised to see the Wildcats making noise in March once again.
