Dach seems to be enjoying himself since joining the two prolific players and the trio is currently having a great run. The last week of the three players, as mentioned by Renaud Lavoie, proves it very well:
It seems that Dach has finally found his place in the organization after a difficult start to the season. If he continues like this, he who currently has 10 points (2 goals and 8 assists) in 12 games, could accumulate more than 68 points, over an 82 game season. Even if he doesn't reach that mark, his contract for three more seasons leaves room for improvement. He could be a bargain in 1 or 2 years, with his $3,362,500 salary, if he continues.
Just think, that's better than the Matthews-Marner and especially McDavid-Draisaitl duos before they were 23. That's pretty impressive and, more importantly, exciting!
