I think this accurately accounts for everything that I see in the chart Dylan shared. Here it is.
Assuming Michigan beats Nebraska:
If Iowa, MSU, and Purdue lose we're a 6 seed against one of PSU, Ohio State or Indiana
If Iowa loses and one of MSU or Purdue win then we're a 7 seed against winner of IU/OSU
If Iowa wins then we're an 8 seed against Illinois
If Michigan loses to Nebraska
If Iowa loses then we're an 8 seed playing Iowa
If Iowa wins then we're an 8 seed playing Illinois
