The argument for the Coyotes being worse at development: Long list of players that they drafted (or traded for at a young age) that are still waiting to breakout (Perlini or Duclair) or broke out once they were traded (Strome, Domi, Turris). Some players there are doubts if they can still be as strong as an impact as a thought like Nick Merkley. It should be noted that while Arizona did make good on some of their draft picks like Keller, Chychrun, Dvorak and OEL a lot of the key players on the team like Kessel, Raanta, Schmaltz, Hammer, and Stepan are not homegrown players and less of their key players are homegrown compared to Edmonton in key roles. The other thing that helps the case for Arizona being the worse team, in this case, is that Edmonton has so far done a good job at developing prospects Kailer Yamamoto and Evan Bouchard.
The argument for the Oilers being worse at development: The Oilers while not necessarily having as long as of a list of players that have failed to work out for them, they have more players that have failed to live up to their draft potential but are still good players and remain members of the team (RNH or Nurse). The other thing that hurts the Oilers is screwing up two very high draft picks, first Nail Yakopov in 2012 at first overall and now Jesse Puljujarvi who was selected in 2016. Yakopov is now out of the league playing in the KHL, while Pulju wants out from the team and will not return to North America unless his rights are traded, with the Oilers not giving him a consistent place (floating from the NHL to AHL and back or lack of consistent linemates).
Summary: The Oilers have more high-profile disappointments whereas the Coyotes have a higher number of them. Vote on which one you think is worse at developing players.
