The biggest story in college basketball is the fact that Memphis has decided to defiantly play what the NCAA has publicly said is a "likely ineligible" student-athlete -- namely James Wiseman, the presumptive No. 1 pick of the 2020 NBA Draft. It's fascinating, unusual and undeniably risky.

It could lead to the Tigers' season being vacated.

It could lead to sanctions on the program.

Basically everything is on the table.

In the meantime, though, it's tremendous theater that'll provide endless storylines Tuesday night when Memphis plays Oregon in the Phil Knight Invitational at the Moda Center in Portland. It's a matchup between Knight's alma mater, Oregon, and the team led by the namesake of one of Nike's best-selling signature shoe lines, second-year Memphis coach Penny Hardaway.

But the story is Wiseman.

The 7-foot-1 center is averaging 22.5 points, 10.0 rebounds and 4.0 blocks in 23.5 minutes through two games. He's been physically overwhelming for the competition so far. Unless Memphis and the NCAA reach some sort of resolution that removes Wiseman from the court in advance of the 9 p.m. ET tipoff, the reigning American Athletic Conference Player of the Week is expected to be in the starting lineup.

Memphis is No. 7 in Tuesday morning's updated CBS Sports Top 25 And 1 daily college basketball rankings. Oregon is No. 14. And Kentucky, which plays Evansville Tuesday night, remains No. 1 for the seventh consecutive day.
