The St. Louis Blues have been a much improved team under Mike Yeo compared to much of their 2016-17 season. Individually, many players have found the spark to turn themselves around as well.
Unfortunately, that is not true of everyone. Though currently both injured, Jori Lehtera and Dmitrij Jaskin have continued to be disappointments on the score sheet even if they have improved somewhat in the effort department.
Lehtera has been out of action since March 10. Jaskin has not seen the ice since March 13. While the Blues might not be as deep up the middle without them, they were not exactly lost in their absence.
