Yeah I honestly don't get this either...
2017 - Yamamoto sent down
2016 - Pulju has spent time in AHL both seasons
2015 - Nobody holds Connor back
2014 - Draisaitl sent down to junior, starts next year in AHL
2013 - Nurse spent 2 more years in junior and started draft +3 in NHL
2012 - Yak, 1st overalls are never held back. His lack of hockey sense and Eakins ruined him, not how quickly we put him in the league
2011 - RNH, was NHL ready, still doing fine.
2011 - Klefbom. Developed for several years and is a #1 dman when healthy.
2010 - Hall was NHL ready. Elite 1st overall pick
2009 - Paajarvi. This is the one that I will argue should have spent some time in the AHL instead of starting in the NHL in draft +2
2008 - Eberle. Waited a couple seasons. Did just fine. Our coaching didn't do him any favours
2007- Gagner. Kid was NHL ready. Coaching ruined him after his rookie season.
That is every 1st round pick post lock-out. The only case one can MAYBE make for rushing players is Paajarvi, but I think he, like our other busts falls more into the part on himself, part on our coaching/environment did him no favours.
