There was a small fad of teams trading down a couple spots from the 1st overall in the NHL, but it hasn't happened in 22 years. Probably just take the BPA and call it a day.
Schaefer (07)-Levshunov (05)
Vlasic (01)-Rinzel (04)
Korchinski (04)-Crevier (04)
Allan (03)
Del Mastro (03)
Kaiser (02)
All the pieces are there in abundance to have an elite defense as long as you don't seriously mess up your asset management or get unlucky with development. By 2029-30 (which is sooner than you realize), you'd hope that's best defense in the league caliber.
Adding to, this will be the age of all the current top 50 scorers in the NHL by then
MacKinnon (34), Draisaitl (34), Kucherov (36), Rantanen (33), McDavid (32), Marner (32), Connor (33), Eichel (33), J. Hughes (28), Reinhart (34), Bratt (31), Scheifele (36), Kaprizov (32), Konecny (32), Necas (30), Makar (31), Hagel (31), Werenski (32), Crosby (42), Point (33), Marchenko (29), Hughes (30), Raymond (27), Strome (32), Pastrnak (33), Panarin (38), Nylander (33), Aho (32), Stutzle (27), Suzuki (30), Guentzel (35), Tavares (39), Monahan (35), Keller (31), Caufield (28), M. Tkachuk (32), Kopitar (42), Kempe (33), Bedard (24), Morrissey (34), Rakell (36), Kyrou (31), Vilardi (30), B. Tkachuk (30), Duchene (38), Rossi (28), Batherson (31), Stone (37), Barkov (34), Larkin (33)
Obviously some of those players will still be around and doing well in five years, but with how "prime heavy" that list looks right now, the NHL is also pretty ripe for a big flip over that time period. Hopefully Bedard is at the very least, highly up there by then, and that through a combo of drafting/free agents/trades/luck, with a clean cap, the Hawks can have a couple more of that next batch.
