1. "Top 10 pick" doesn't mean anything. In a typical draft year, there's a BIG difference between the guy drafted 1 and the guy drafted 5. Unless we're talking about a #1, #2, or sometimes a #3 pick it's all a big crapshoot.
2. Management, coaching, scouting, and player development have all turned over since Klesla and Moore were selected. If we want to talk about picks getting squandered, we should probably start in 2013 which was the first full draft under current management. Between then and today, we have four players drafted in the top-10. Werenski, PLD, Johnson, and Jiricek. Again, refer to #1 above about how I think there's major differences in expectations even amongst #3 overall (PLD) and #8 overall (Werenski) but I find it hard to argue that any of those players are misses in terms of drafting and development.
3. 2013 is interesting for another reason - in the 2012-2013 season (which was shortened by a lockout), last year's Stanley Cup winners the Colorado Avalanche finished last in the Western Conference and 2nd to last in the league with a 40% points percentage. They drafted franchise center Nathan Mackinnon 1st overall. They made the playoffs in 2014 and exited the 1st round. Then in 2015, 2016, and 2017 they missed the playoffs. In 2017, they had the worst record in the NHL and ended up drafting last year's Norris and Conn Smythe winner Cale Makar 3rd overall.
Honestly, I'm don't see the cause for alarm here. Jarmo has shown an ability to draft and develop high picks. Further, the strategy of bouncing between being competitive and bottoming out clearly can work - See Colorado and then Chicago and Pittsburgh before them.
He isn't perfect. This is a cap squeezed roster that is bottoming out. He did sign Gudbranson. He did move Bjorkstrand. He has made some bad picks (particularly between 15-35). And I don't like his coaching selection with Brad Larsen. But in terms of judging his ability to draft and develop, he did it once with PLD and Werenski and got us to an 100 point season. He could do it again.
