Update league standings on website?

I had a potential customer call me about taking over his wordpress website, www.hazelwoodcorp.com. I told him that I would redesign it in Webflow. But on his current website he has links to html files that show current standings for all of the dart and pool leagues. He said he updates these html files and uploads them with filezilla to his wordpress site. Can this be done in webflow? If so, how?
