The Tampa Bay Lightning are in the midst of one of their worst stretches of hockey during the regular season in a long time. They are 7-8-0 in their last 15 games and have alternated wins and losses in their last seven outings. The good news is they host the Columbus Blue Jackets, who are in a freefall, on Sunday. The Blue Jackets have lost eight straight games since beating Tampa Bay on April 6, and have lost 15 of their last 17 games overall. If the Lightning can’t take advantage at home Sunday, it will say a lot about the status of this team heading into the postseason.
