While discrepancies between NHL.com and other sites are sometimes caused by empty net situations, that is not always the case, and that seems to be a particularly questionable cause when discussing the PP, especially when your 5v4 numbers are inconsistent with other sites as well.
Looking at Spezza for example, and his per-60 production and listed TOI, we can test this, and can easily see that the site you are using has credited Spezza with a higher number of PP points that he does not actually have. This is not just empty net issues.
Since we're talking about a game state with inherently small samples, and Spezza in particular has such low PP ice time overall, small mistakes in the inputs has a significant impact on his per-60 rates. Also, you talk about role and QOC impacts quite a bit, but seem to have dismissed these in a discussion where role and QOC differences are quite substantial.
You also say how this isn't just about the past couple weeks, but Marner was even higher than his 2nd place rank - sitting at #1 in PP P/60 over that same time period at the time of his injury, so yeah, it is kinda all about the hot streak the past couple weeks that Marner hasn't been able to benefit from like everybody else.
you're right there are a couple point discrepancies. unfortunately nhl.com still doesn't isolate for 5v4 situations so let's see if i can hack the difference.
I'll look at isolated 5v4 PP numbers from both E-H and NST and use the numbers which make Mitch look best and the others worst.
Mitch
EH: 396.68, 3 g, 19 a1, 16 a2 = 22 p1, 38 p = 3.33 p1/60, 5.75 p/60
NST: 398.80, 3 g, 19 a1, 16 a2 = 22 p1, 38 p = 3.31 p1/60, 5.72 p/60
Matthews
EH: 434.85, 27 g, 9 a1, 8 a2 = 36 p1, 44 p = 4.97 p1/60, 6.07 p/60
NST: 438.67, 27 g, 9 a1, 8 a2 = 36 p1, 44 p = 4.92 p1/60, 6.02 p/60
Tavares
EH: 385.85, 16 g, 14 a1, 8 a2 = 30 p1, 38 p = 4.67 p1/60, 5.91 p/60
NST: 385.51, 16 g, 13 a1, 8 a2 = 29 p1, 37 p1 = 4.51 p1/60, 5.76 p/60
Nylander
EH: 376.29, 17 g, 11 a1, 10 a2 = 28 p1, 38 p = 4.47 p1/60, 6.06 p/60
NST: 378.76, 16 g, 11 a1, 10 a2 = 27 p1, 37 p = 4.27 p1/60, 5.86 p/60
Spezza
EH: 178.12, 6 g, 10 a1, 3 a2 = 16 p1, 19 p = 5.39 p1/60, 6.40 p/60
NST: 178.50, 6 g, 10 a1, 2 a2 = 16 p1, 18 p = 5.38 p1/60, 6.05 p/60
So using the best for Mitch and the worst for the others:
P/60
- Spezza 6.05
- Matthews 6.02
- Nylander 5.86
- Tavares 5.76
- Marner 5.75
P1/60
- Spezza 5.38
- Matthews 4.92
- Tavares 4.51
- Nylander 4.27
- Marner 3.33
So when looking at an apples to apples comparison, at 5v4 only, we again see that Mitch's overall production is at best close to the others, but that his primary point production is we behind them.
I haven't dismissed anything, and you haven't provided evidence of the claim. On the contrary, you attempted to dismiss the evidence provided to you by making vague, unsupported comments about "super duper chances" and putting down the stat (and a bunch of additional complimentary stats) that you constantly use.
you have dismissed all of:
1. actual goals
2. the relevance of primary vs. secondary points
3. potential issues with xgf on the PP specificially
You have also relied on complete-5-man-unit splits to dismiss the much larger sample stats we have.
Marner has not "dominated the puck on every PP for years now". Good lord.
Gotta be honest - not sure how anyone who watches the team could disagree with this.
You certainly want your best playmaker handling the puck more than your goal-scorers, but if anything, he's been controlling the puck on the PP less and less as the unit has become more and more stacked. This whole "PKs leave him open!" and "goalies know what's coming" and "every time the PP isn't on fire is Marner's fault!" stuff is pure garbage.
I think you might want to consider that there's truth to it. Otherwise it's hard to understand why "our best playmaker" is so far behind the others in primary point production.
Again, I never suggested that different roles shouldn't be tested, and I specifically agreed with riding hot streaks (which we were on with Marner as well, for the record), so I'm not really sure what you're even arguing, or what in my original post you disagreed with, especially since you seem to agree with my main point that Marner should be kept on the top unit.
Well ok if you don't want to discuss it that's fine.
Myself, I think it's unfortunate that it has taken mitch being forced off the top unit due to injury for us to finally see something a little bit different on the PP - and I'm not surprised at all that the PP has kept clicking right along without him, and has arguably looked faster, more decisive, and created more wide open goalie-way-out-of-position bang in chances (yes, super duper chances) than we've seen in a while.
