He was never as good as hyped, but to end up with what Yakupov ended up as without some career-altering patch of injuries like Patrik Stefan, it is a complete it takes a meeting of a bunch of massive issues. The others were he was absolutely terribly developed and coached, seems to have suffered a massive loss of confidence which could never be refound in key development years. With guys that highly thought of, sometimes they just don't have the IQ, but you can usually harness their talent into some sort of decent 3rd liner such as the Sam Bennett situation in Calgary or Virtanen in Vancouver (although Virtanen has raw physical tools which others lack like Chad Kilger). Outside of the clearly elite talent that was McDavid and Hall, who were essentially sure things, and the exception that is Draisaitl, they had clear trouble getting other guys to reach something approaching their ceiling with Gagner, G. Reinhart (although, Isles eat part of that), Puljujarvi is a wait and see, but he sure isn't trending well). RNH is still a good player, but hasn't approached close to what people expected out of him from him at 17 and 18. Nurse is performing about par for where he was picked, not above or below it. Klefbom is probably there best non-Draisaitl development story. Maybe some of these younger guys will change the trend in Yamamoto (I'm not going to put too much weight into a very small sample size from this year playing with Drai against previous NHL and AHL play) and Ethan Bear (whose had a promising start to his career). Tyler Benson should be a good player for where he was picked if he can become a consistent 3rd liner. So, maybe some of their more recent draft pick developing under the new regime (while drafted under Chiarelli) will provide the depth they will need to consistently contend with their two high-end top pieces.
