USA Today's sports lines are available on the Sports section of USAToday.com, as of 2015. The site lists available lines for each sport under that sport's Odds page.
To view sports lines on USAToday.com, visit the site's home page and click Sports. On the Sports section, place the cursor over a sport. On the menu that appears, click Odds. For some sports, the site lists the Odds link under More. If so, place the cursor over More first, and click Odds on the drop-down menu that appears.
Not every sport has lines available. For those that do, USA Today lists odds for upcoming games. It provides odds from multiple casinos.
