The St. Louis Blues are definitely in an odd spot right now. The players, and even the front office to an extend, still need to be focused on a potential finish to the 2019-20 season, even if it is only a truncated playoff system.
That said, you cannot ignore the future, as uncertain as it might be. The Blues have to make preparations for 2020-21 and beyond and look at all avenues for improving the team regardless of whether 2019-20 ever comes to an end.
The Blues are pretty set with all their main players signed through 2021 and the only free agents being restricted.
