Nebraska: For varsity (for the most part) 5-man crews. Some schools (especially at the 8-man level) might use 4-man crews still. Sub-varsity is usually 4-man crews for JV games (at most places) and 3-man below that. Playoffs are all 5-man crews.

Iowa: Speaking varsity only, it's pretty much 5-man all over, although there are a few schools who go 4-man crew. Playoffs are all 5-man crews.
