Here is how I import it.
Open a new Excel sheet with cursor in the A1 cell.
Click on the data tab, then clock on the "From web" icon (second from left).
It will open a "new web query." Copy and paste the web address for your team stats (something like this: https://www.whatifsports.com/hd/TeamProfile/Stats.aspx?tid=11946)
That page will load. It may ask you if you want to continue running scripts. Click yes. Once the stats page fully loads, hit "Import."

The other way to do it is to download the "Scraper" extension for Chrome (https://chrome.google.com/webstore/detail/scraper/mbigbapnjcgaffohmbkdlecaccepngjd?utm_source=chrome-app-launcher-info-dialog). If you highlight one line of stats on your team's stat page and right click "scrape," it will pull all the stats off in a format that makes for easy copy/paste into spreadsheets. This extension was a godsend during 2.0 recruiting.
