I knew Michigan was out but didn't realize so many other teams were out as well. Here is my list
Men
Iowa - competed but didn't run a full team
Maryland - Did not compete - no team
Northwestern - Did not compete - no team
Michigan - Did not compete (covid-19)
Rutgers- Did not compete - Covid-19)
Any disappointed in Iowa ? They had 3 finishers. Why didn't they get two sprinters on the track team to walk the course?
If they had been in the team score, they would have beaten Ohio State. There 3 finishers would have been 40-44-46. Then if they had two more athletes in last, it would have been 67 and 68, giving them a team score of 265. Ohio State was last with 256 but if you put the Iowa guys in the team score, it adds to Ohio State's score and gives Ohio State 270. So Iowa would have beaten someone.
For the women, here is the list of teams that didn't record a team score.
Iowa competed but didn't run full team
Maryland - Didn't compete, not sure why - no schedule listed on website
Rutgers - Didn't compete Covid-19
Michigan - Did not compete (covid-19)
