If we're grading players at the quarter-pole, relative to role, salary, and expectations, this would be my take :
Goalies
Luongo - B. It's a different Luongo than a few years back. He's no longer elite, and struggles a bit with his athleticism and mobility. Doesn't get to pucks that he used to. But he's battling hard, his rebound control has been very good, and he's been clutch at making the saves he's needed to late in close games.
Lack - B+. Numbers are matching Luongo's as a bargain-basement rookie backup. Nice start to his career, has looked good.
Defense
Bieksa - A. Has been our best defender, and many nights our best player. Still makes the occasional head-scratching blunder, but those have been outweighed by loads of terrific plays to drive possession.
Hamhuis - C+. Was horrible the first 5 games. Since then, he's rebounded and has been very good. Except on the PP, where the decision to continue using him on the #1 unit is perplexing.
Garrison - C+. Reverse of Hamhuis. Started great the first 10 games, has looked poor for the past 10. Struggling at both ends of the rink right now.
Edler - C-. Our most disappointing player so far. Hoped that healthy with a new coach, he'd have a breakthrough as a top player. Instead, he's regressed. Is being overplayed, and now a -7 on the season. Struggled on the PP and not contributing offensively. Should not be seeing minutes against top lines of the opposition - seeming to have major troubles reading the play on the rush, and way too many guys are getting in behind him. I was opposed to the idea of trading him last summer, but in hindsight it would have been a good idea given the way Tanev and Stanton have played. Needs a major turnaround.
Tanev - B+. Great on the PK, seeing top-4 minutes most nights (ahead of Garrison lately). Sometimes goes for a shot block at a bad time, but generally has seen a massive step forward in his play at both ends of the rink.
Stanton - A. Waiver pickup has been rock solid, and looks like he could handle more minutes than he's playing. Only Bieksa has more points at ES, and his composure with the puck has been frankly astonishing for a guy coming in with a reputation as a low-even defensive banger. Will be a top-4 NHL defender in the future.
Weber - Incomplete. Hasn't played more than a couple shifts at forward. The fact he wasn't used on the point on the PP given how dreadful we've been there is bizarre.
Alberts - F. Terrible player. Coaching staff has no confidence in him. Unplayable. Why is he still on the roster eating cap space?
Forwards
Henrik - B+. Would have been an A until poor recent road trip where he struggled. Has still been easily the team's best forward.
Daniel - C+. Being carried by his brother at times. Games 5-15 were much better.
Kesler - B-. Scoring goals when with the Sedins. Doing nothing offensively otherwise. Was a beast defensively on the long road trip, though.
Santorelli - A+. Best forward not named Henrik. Has busted his ass in all three zones on every single shift, and reward with results offensively. Great signing.
Higgins - B+. Couldn't buy a goal early, but on pace for 25 now. Just a solid contributor at both ends of the rink.
Hansen - C. Play was a little off by his standards early, then got hurt.
Burrows - C. Cutting him a little bit of slack because he was injured. But 2 points in 8 games simply isn't good enough. Does not look like a top-6 player when separated from the Sedins. Really wonder how bad that new contract will look in a couple years.
Kassian - C. Incredibly hit-and-miss. Had some very good games on the road trip and seemed to be showing progress ... then was terrible in the past couple games. Needs to keep his feet moving and find some consistency.
Booth - D. Yuck. Shame we couldn't buy him out last summer. Hopefully the AHL stint wakes him up and we can get a bit of value out of him before buying him out next summer.
Richardson - A. 4th line center has 10 points in 20 games, great on the PK, and does all the little things well. Excellent signing.
Weise - C+. Usual solid 4th line play before his injury.
Sestito - D. He stinks, and to me is a waste of a roster spot, but he's had a couple better games lately.
Dalpe - D. Has done zilch so far. The one off-season acquisition who hasn't worked out. Needs to go to the AHL and get some minutes and confidence.
Archibald - B. Not quite ready but showed well, and will be up again before the season is out. Big body who finishes his checks. Needs to get stronger on the puck along the boards in his own zone.
Welsh - B. For a nobody throw-in to the Dalpe deal, he's looked pretty decent. Supremely low-event player, but a big body that can chew up 10 minutes/game without hurting you isn't a poor system asset.
Schroeder - incomplete. Injured twice. Clock is ticking, and you have to wonder where he fits here.
Coach
Tortorella - B+. Has done everything well except for the PP, which is a total disaster. But the team looks prepared and hard-working, PK is great, hasn't done anything controversial yet. Positive change.
