Going a bit off-base I just have to mention that Douglas Murray is the grandson of former Swedish star defenseman Lasse Björn. I guess at the NHL level Murray is more accomplished, though nowhere near a star player.
Lasse Björn, a contemporary of legend Sven Tumba played over 200 games for Tre Kronor, many of them as team captain, and won the Swedish Championship a record 9 times with Djurgården. Curiously enough he was known as a big, tough hard-hitting defenseman. Apparently Murray says that his granddad has learnt him a lot about what it takes to play defense!
Unquestionably, Douglas still has a very long way to catch up with his grandfather though.
So to take this topic to the next level, are there any
grandsons currently eclipsing their forefathers?
