Some decent ideas.
Mine would be make the draft lottery the morning before the actual draft, not behind closed doors but on a stage where everyone can see, also make it into a spectacle like the NFL but bigger, whichever city it's in get celebrities from the area who enjoy the NHL to come out. If it's a Canadian city have celebrities like Jim Carey, Keifer Sutherland, Ryan Goessling, The Rock, and have like Justin Beiber come out and sing some tunes. Instead of all the prospects being in the stands have them backstage chilling with each other. Also before the lottery and draft have the trophies being handed out for lady bing, Art Ross etc.
