With regard to 2010
1) Kevin Hayes decided not to sign with Hawks, not sure what you expected Hawks to do when a guy who if he would have signed would have been our #1 prospect decides he isn't signing
2) Nordstrom was solid depth player who was a part of 2015 SC winning team. When your 3rd rounder plays 444 games (+46 Playoff games) that is great value for any team at draft
Did Hawks blow alot of draft capital that year? Yes, and not signing Holl turned out to be mistake but overall can't really blame Bowman for Hayes situation IMO at this point looking back
With regards to 2011
1) Are we pretending Andrew Shaw does't exist?
And Teravainen made big impact in 2015
Again the biggest problem was asset management of young talent. Trading away Danault, Teravainen, etc is where problem lies and why team ultimately fell apart
