You realize if you remove 11-12 and 12-13 from the discussion his numbers become: 24 GP, 2 goals, 4 assists in 15:50 ATOI. Which translates to 0.25 points per game or 0.95 points per 60. He gets worse when you take out those 18 games from the first part of his career.
For someone who is willing to write off a 19 year old overmatched in his jump from the WHL to the NHL, I'd expect you to at least understand a statistical performance based criticism of a player who has been a terrible playoff performer through the prime of his career. Yes, the Red Wings weren't the best team in the playoffs from 13-16, but I would expect better than 3 points in 17 games. Yes, he has shown signs of improvement playing on a better team, but he still isn't the same player in the playoffs as he is during the regular season.
