The St. Louis Blues are likely done with the free agent market, unless something truly unique comes their way. However, there is still a small chance for them to add another winger, but it depends on a couple things.
The most interesting name left in free agency, at least in terms of what might benefit St. Louis, is Mike Hoffman. Hoffman is a steady scoring threat, which is just the sort of thing the Blues could likely use in 2020-21.
St. Louis is going to be without Vladimir Tarasenko for who knows how long.
