I posted this back in mid January and it still applies now IMO.
I'd be very surprised if he doesn't make the opening night roster to be honest.
His defensive play is pretty fantastic, there's a reason he's put out heavily on the PK and in key situations. His play in the defensive and neutral zone is fantastic, it's the offensive zone where there is struggles as he's not great with generating chances with the puck on his stick. On the flipside, as I said above, his forechecking and physical play is really good which opens up opportunities for his linemates which has been the case when Sidorov was on their line earlier in the season, and more recently Myatovic. Both Sidorov and Myatovic have have had their best production on the Gaucher-Caufield line opposed to away from it so far this season.
It just depends what your expectations are for Gaucher. Are you expecting a middle 6 forward to chip in 15-20 goals a season? I'm not sure Gaucher has that in him. But I can see him as an excellent defensive forward that can chip in 10 goals a season while being the #1 defensive forward on the team and being a heavy physical presence.
+/- isn't a fantastic stat but when you consider how terrible the Gulls are at ES (93 scored v 121 conceded) and Gaucher has 8 points yet is only a -3...he's been pretty damn good at not being on the ice when goals go in.
I think Gaucher will be a nice change of pace from our extremely soft 4th liners of recent years and will provide some good defensive value in our bottom 6.
(I'm not going to get in whether Gaucher was worth the pick or not, just my opinions on where he slots in).
