Solid squad. I'd say that there is going to come a point where you want to trim your goaltending to just three and maybe even two guys but you've done a good job of grabbing some backup plans in case someone doesn't work out. Ultimately, with only one counting stat (wins) and two ratio stats (GAA and Sv%) there is more value in having a couple of high quality goaltenders than to have several mediocre ones.
Eventually your goal should be to have two goaltenders you can count on so that you can roll as many bodies out at forward as possible since all skater scoring is counting.
You also might reach a point where you want to only carry five defensemen since forwards will typically offer you more offense. You can likely get more bang for your buck by rolling with five defensemen and extra forwards especially since you start so many forwards every day.
If I was to do anything with your team I'd try to deal a defenseman (I'm thinking Doughty because he is fairly overvalued) and a goaltender (probably Fleury) to land a top flight goaltender. Maybe that deal isn't possible but I'd kick the tires and see if you can shake loose a Lundqvist, Rinne or Quick because they offer a big step up over every other goalie in this league.
