I just heard the replay of an interview given by the ex-head stooge at DansLesCouillesLisses.
He said that he attended this 3 vs. 3 league featuring pro players and which included Slaf, Suzuki, Josh Anderson and several NHLers. Apparently, a spot opened for Slaf on account of Huberdeau bailing.
The game is played on an undersized ice surface. The stooge said that Slaf held his own and reminded him of a faster Malkin. Said he looked very close to being NHL ready.
One drawback he noted was that unlike the other players, Slaf looked visibly winded by the middle of the 2nd period. Don't know if it's a one-off or if he's that badly behind, fitness-wise.
What's interesting is that admission is only $5 and you get to see the players really close up. Apparently, the place has been packed every game. Proceeds go to charity.
I don't know where the league is at, but they were in playoff mode around mid-August. League may have completed its schedule, I'm not certain:
