First of all, any article that quotes Chad DeDominicis has to be viewed suspiciously. No knowledgeable Sabre follower takes him seriously.
Second, I would never say Mittelstadt was a lock for #2 center, in fact, I would have sent him to Rochester last year after watching him perform in the Sabre's Prospect Challenge.
Third, he is hardly a bust, with 39 pts in 114 NHL games as a 20 year old.
Fourth, the article was correct, it was a terrible draft which should have automatically meant he should not have been brought into the NHL as soon as he was.
Fifth, while he did get PP time, he made the most of it getting more goals than Sam and was ranked 5th among all Sabre forwards with 10 PP pts. Let me add, he only averaged 13:27min/game in 2018-'19 which was less than Larsson or Girgensons. So to say he got mid six minutes would be a gross exaggeration.
Sixth, he needs to get bigger just as Sam Reinhart did. Once he does that and his ceiling is only 40pt, then I would be disappointed.
