Volunteers have helped clean a dozen homes, but officials said more than 50 still needed work, the newspaper reported.
For the football players, tackling this job was their civic duty.
"We feel like it's kind of our job to go and help them after they helped us," Willett told the Herald. "Even if it's just moving something for your neighbor or even cutting their whole carpet in their downstairs basement like we are, anything helps."
"A lot of people are happy to see us there. So it always feels good," senior Evan Pederson, a middle linebacker, told the newspaper.
The Salvation Army and Community Organizations Active in Disaster is still seeking volunteers to remove wet rugs and Sheetrock from homes before mold sets in.
"It devastates me — volunteers are vacuuming up water from basements all over Grand Forks," homeowner DeLaine McGurran told the Herald, "I personally am a little challenged so I can't do a lot down there. I've had two hip replacements, and I've almost fallen because it's a slippery tile."
"The quicker it can get out, the quicker things can get dry -- the more likely that you aren't going to deal with mold and all of the other bad health effects of it," Mark Ellingson, chairman of COAD, told the newspaper.
