Since taking over behind the bench for the New York Islanders in 2018, Barry Trotz has had a fairly stable roster. There's been little turnover on the roster.
That's mainly thanks to GM Lou Lamoriello making just a single trade over the last two seasons. But the roster has also seen such stability thanks to having a fairly healthy roster. In 2018-19 the Islanders ranked 19th in terms of man-games lost. Most of that was due to Andrew Ladd.
Now this season, the Islanders are already up to 15th in the league in terms of man-games lost.
