Yeah, I wouldn't downplay the Islanders either, they've stiffled offensive teams come playoff time, their issue is the LA Kings issue where they're built for the playoffs but you can't play that style for 82 games, they just need to make it in anyway they can.
Honestly, watching Point play without Kucherov the last 2 seasons I'm not sure he'd do better than Barzal on the Islanders either, at least in the regular season that is. A whole lot of going in circles and doing nothing, both of them need to feed off another skilled player but Barzal doesn't exactly have one.
