Somehow, we’re already at the end of the road for another Big Ten basketball season. But the good news is hardly anything has been decided.

Wisconsin enters the final week with a tenuous 1-game lead over Purdue and Illinois for the regular-season title and the No. 1 seed in the Big Ten tournament. Win out, and the Badgers are also in line for a potential 1-seed in the NCAA tournament.

There’s also an interesting battle brewing for the No. 4 seed in the Big Ten tourney, which comes with an all-important double-bye into the quarterfinals. Ohio State is a game ahead of Michigan State and Iowa for that spot.

And then there are the bubble teams.

Michigan, Indiana and Rutgers could all use another win or 2. And they’d probably prefer not waiting until they arrive in Indianapolis next week to get them.

So without further ado, here are our B1G 3 games for the week of March 1-6, ranked in order of entertainment value.

 No. 8 Purdue (24-5, 13-5) at No. 10 Wisconsin (23-5, 14-4)

When: Tuesday, 9 p.m. ET, ESPN

Why it’s B1G: This one is for all the marbles. Or a share of the marbles, depending on who wins.

With a win, the Badgers will wrap a bow on their first unshared Big Ten title since 2015. All that would be left to do is beat Nebraska at the Kohl Center, which might be achievable if every Badger shoots exclusively left-handed for that game.

Purdue needs a win for a chance to add another year to its Big Ten championship banners at Mackey Arena. And much like the Badgers, the Boilermakers are in line for a potential 1-seed in the Big Dance should they win out. Lose this one and Purdue might be stuck on the 3-line come Selection Sunday.

Wisconsin won when these teams met at Mackey on Jan. 3. That was the day Johnathan Davis became Johnny Davis, exploding for 37 points and serving notice that he would be a factor in the national player of the year race.

However, it was also a revelatory game for Purdue center Zach Edey. That loss marks the last time Edey didn’t start for the Boilers, as he came off the bench for 24 points in 20 minutes.

It will be fun to see if either defense has an answer for these breakout stars this time around.

No. 24 Iowa (21-8, 11-7) at Michigan (15-12, 9-8)

When: Thursday, 9 p.m., FS1

Why it’s B1G: Every game is vital to the Wolverines, who probably need to hit 18 wins before Selection Sunday to feel comfortably in the field.

But this game is not unimportant to Iowa, either. As noted, the Hawkeyes still have a chance at a top-4 seed in the Big Ten tourney. And winning 3 games in 3 days is decidedly easier than winning 4 games in 4 days.

Stakes aside, this matchup is just plain fun. Michigan beat Iowa 84-79 at Carver Hawkeye Arena on Feb. 17, and the 80-point mark is attainable for both teams this time around. The Wolverines played some of their prettiest basketball in the first meeting, with assists on 21 of 31 field goals.

Michigan will have to keep clicking, because it seems unlikely Iowa will again shoot 22.2% from 3-point range. That 4-for-18 showing is Iowa’s third-worst outside shooting performance this season.

Rutgers (16-12, 10-8) at Indiana (18-10, 9-9)

When: Wednesday, 7 p.m., BTN

Why it’s B1G: This feels like a “win and get in” scenario for both teams.

Including the Big Ten tourney, Rutgers probably needs 2 more wins to get to the NCAA tournament.  The season finale against Penn State should take care of half that equation.

Indiana is in a position where just 1 more win will likely do the trick. But with a trip to Purdue looming in the regular-season finale on top of a potentially tough Big Ten tournament draw, this game likely represents Indiana’s best chance to get that W.

Stylistically, this will look as different from the Iowa-Michigan game as is conceivable. Both teams play gritty defense and are comfortable playing in games that devolve into rock fights.

Honorable mention

No. 24 Iowa at No. 20 Illinois (Sunday, 7:30 p.m., FS1): The Hawkeyes and Illini close out the Big Ten schedule 3 months to the day after their first meeting.

That game was plenty entertaining, with Illinois holding on late for the 87-83 win. In the rematch, the Illini potentially have a chance to clinch a share of the Big Ten title and the top seed in the conference tournament.

Iowa could potentially wrap up the No. 4 seed and enter the tourney having won 9 of its last 10 games.

Michigan State at Michigan (Tuesday, 8:30 p.m., Fs1): You’ll need some sort of 2-screen solution as the majority of this game goes head-to-head against the Purdue-Wisconsin showdown for the crown. But it will probably be worth it. The Spartans surely relish the chance to help burst their rivals’ bubble.

Michigan State at Ohio State (Thursday, 7 p.m., ESPN): Kind of like the Purdue-Wisconsin game, but for the last double-bye in the Big Ten tournament. With a win here, the Buckeyes can pretty much put the Spartans and Hawkeyes in their rearview mirror.

If Michigan State wins, all sorts of chaotic possibilities could play out on the season’s final weekend.
