Seeing a glimpse of their potential goaltending future gave Devils’ fans something to cheer about Tuesday night – as did a too-little-too-late comeback attempt. Everything else from the Devils is almost too ugly to contemplate right now, however, after they dropped their sixth consecutive game, 5-2, to the slumping Tampa Bay Lightning at Prudential Center. The Lightning built a 4-0 lead and held on to snap a five-game losing streak, chasing struggling Devils goaltender Johan Hedberg 13:13 into the second period. That brought 23-year-old rookie Keith Kinkaid off the bench to make his first NHL appearance. Kinkaid, who signed with the Devils as an undrafted free agent out of Union College in 2011, stopped 12 of the 13 shots he faced. Devils coach Pete DeBoer made it clear immediately afterward, however, that Hedberg will start again Thursday night against Buffalo, saying, “We’re going to go back with Heddy.”
