The Oilers don't care about developing youth, never have as long as I've been a fan, almost 30 years now although in the late 90s, early 00s they had to trade away young talent due to financial restraints.
Look at their drafting even going back to the latter portion of The Glory Years even before I was a fan, just putrid.
Ironically, Holland did well to draft Holloway and Broberg and they were on a good development path (an Oiler rarity) then they still botch it because he had no idea how to manage a salary cap and JJ got vet hungry on Day 1 of Free Agency then Bowman was left scrambling to find a way to match, still blame him for not creating 900K of extra cap space to match Holloway, unforgiveable. An unholy trinity of f*** ups by those 3 overpaid GMs.
The Oilers had a real chance to extend the Cup window with Broberg in line to replace Ekholm's minutes once Ekholm took a more diminished role and Holloway to replace some of the older forwards or merely take a wide open spot right there on Drai's LW and now their Cup window has shrunk to virtually nothing. They'll always be competitive as long as McDavid and Draisaitl are top players but their primes are on the clock so once they fall off even a bit, the Oilers are cooked unless a new GM can create some magic. The new McDavid and Bouchard contracts are going to cripple them too but it would have been an easier pill to stomach with strong youth flanking them even though, yes, Holloway and Broberg would also have to be paid in 2 years.
