If he is brought in to replace Malhotra, the team may gain some offense, but could lose in faceoff results. Would the potential offensive gain be enough to off-set those possible defensive zone faceoff losses? He is signed to one more year at $1.7 million which is below Malhotra's contract (which expires at the end of this season).
If Goc was brought in to replace Lapierre then there would likely be a gain in offense, but there would also be a loss in team "toughness" and someone who fills the agitator role which, to my understanding is not a role that Goc can fill.
If Goc was brought in to replace Shroeder, this would be a bit of a no contest purely due to Schroeder's inexperience.
The point of including Goc in a deal is not to run down any of the Canucks roster centers nor is it to replace them. I was also looking at the players these guys are in recent history - as in the last three years (in other words, what can be reasonably expected of them at this point in their careers).
I am a believer that you can't have too many quality centers on your roster and I prefer the bottom six to have a pair of centers on a line, particularly the fourth line with it's huge load of dzone starts. Manny and Lappy together on the fourth imo make it a formidable shut down line - that allows Malhotra to approach dzone faceoffs very aggressively without fear of being waved because he has Lapierre on his wing to back him up. I don't look to Lapierre for secondary scoring - imo that's not really his role, not his strength and shouldn't have to be his focus.
I really like Schroeder - I had no doubt he'd step in and show that he's NHL ready - I don't expect marquis production from him out of the gate, but I like the depth, speed and youth factor he brings to the lineup. I wouldn't consider him an ideal third line center but certainly wouldn't be concerned if the Canucks need him to play that role, particularly if they're healthy enough (Kesler) to leave the pair of centers on the fourth line, taking some onus off the third, and not needing him to be a 2C as a rookie. Schroeder imo might be a nice option to double up on Kesler's wing.
Having Goc however, does a few things. I takes pressure off of Kesler (as Pahlsson did) - it gives the third line that dual shutdown/secondary scoring potential, and it gives the Canucks depth at the right position - they also happen to have three depth centers who are UFAs in months. It is also insurance as we simply don't know how Kesler will heal or if he will remain healthy throughout the season.
If a deal includes a young, two way center who is NHL ready, great. Shore may be enough depth to bridge the depth, but of the roster forwards Florida has, he'd be my choice. As I said before, he doesn't need to be a massive upgrade over Manny and Lappy - that's not the point imo - and if we're dealing with Florida, I'd prefer the bulk of value be spent on futures.
