After being drafted 4th overall in the 2016 NHL, Puljujarvi has developed slower than the Oilers would have liked. Other players in that draft taken after him making an impact include Matthew Tkachuk, Clayton Keller, Charlie McAvoy and Mikhail Sergachev. There are also players who have earned a spot playing regular NHL duty including Pierre-Luc Dubois, taken 3rd, and Jakob Chychrun.
The Oilers have a player in Puljujarvi who has the speed, skill , and size to be an impact player at the NHL level. With the teams lack of speed and high end skill, they need him to make this recall a permanent one.
