There are four players on the entire team from before Dubas started: Rielly, Johnsson, Gauthier and Nylander. There's also Engvall who seems to have NHLer written on him.
From when Lou started (though Kyle was working under him at the time) we have: Matthews*,
Andersen, Liljegren*, Korshkov, Woll.
Matthews was an easy #1 pick and Liljegren was also a no brainer. The one piece Lou deserves big credit for is Andersen.
Not counting the recent draft (which many pundits say they did quite well at) or the recent signings that may be NHL or AHL, just NHL bodies or ones seeming to currently have higher potential but here's how the rest looks under Kyle: Marner, Dermott, Hyman, Kapanen, Tavares, Muzzin, Barrie, Spezza, Kerfoot, Ceci, Bracco, Sandin, Lindgren, Timashov.
There is one player on this team that has been on the team more than three seasons and four in the organization for more than three seasons and most of what is here is under Kyle's watch.
He's got some bigger contracts but for the first time ever, they are all on the guys who should have bigger contracts and who are either entering their primes or in their primes.
While being tight to the cap, he dealt with his crappy inherited contracts and addressed RHD by adding potentially two top 4 RHD (albeit temporarily) and not giving up any of his top 3 prospects at the time. He's twice traded down and secured Sandin, Dermott and Bracco.
Just about the only complaint to be had is contracts to stars but again, at least it is being spent in the right places.
Will be interesting to see how he manoeuvres next season.
