621: Surprising Habs and Sabres; Tkachuk's Debut; Karlsson and Hoffman; Mike Bossy's Cancer Battle

Brady Tkachuk debuts Thursday night against Erik Karlsson and the Sharks. Karlsson still doesn't lack for confidence. There's clearly no love lost between he and Mike Hoffman. they got into a little as San Jose pounded Montreal 5-0. The finalists are 0-4 while Buffalo – expected to be doormats – have begun the year 3-0. Jack Eichel can't be loving that. NHL legend Mike Bossy is dealing with lung cancer.
