What to Watch in Friday's Big Ten Quarterfinals

The Michigan vs. Ohio State quarterfinal is the marquee matchup of the day. The rivalry always carries extra weight and a Big Ten Tournament setting sharpens it further. Ohio State enters on the strength of a gutsy win over Iowa, while Michigan comes in rested with a bye through Thursday.

Illinois vs. Wisconsin sets up as a battle of contrasting styles. Wisconsin is coming off back-to-back games after surviving Washington, while Illinois has been off and fresh. The Badgers' fatigue could be a real factor late in that one.

Purdue enters as one of the hottest teams in the bracket after rolling Northwestern by 13. The Boilermakers have the size and experience to make a deep tournament run, and Nebraska will need a complete 40-minute effort to slow them down.

The Big Ten Tournament continues Friday exclusively on CBS and Peacock.
