We need to be careful not to gloss over the actual facts with broad statistical analysis, especially now that so much specific information is available to us. In Denneny's case, he doesn't even need the broad analysis. He was the leading scorer on three Cup winners. That's enough to tell me that he brought his A game in the postseason.
But seriously...there are a lot of bad statistics out there, and sweeping, career-wide playoff PPG stats are among the worst. I am also not a big fan of GF/GA statistics which completely ignore known and significant external factors. I will offer an example which will surely annoy overpass, but is nonetheless telling:
If you read the bio overpass did on Chris Pronger, you will see that he rates Pronger, by virtue of power play efficiency statistics with Pronger on the ice, as one of the best PP defensemen of the last decade, and adds this comment in summation:
Although I have a lot of respect for overpass as a hockey mind, this is an abuse of statistics. Why? Because Chris Pronger has spent almost his entire career as the second best power play defenseman on his own team. He was paired on the powerplay (and often at even strength) with Al MacInnis in St. Louis and then with xxxxxx (although normally not at even strength) in Anaheim. Of course Pronger's power play goals-on-ice-for numbers look great. He has had an inordinate amount of help.
A specific two year sequence of events in Pronger's career is rather telling. Pronger played the top pairing in St. Louis with MacInnis for a long time, and that was a very effective power play. Then Pronger misses almost the entire season in 02-03 and the Blues' power play actually improves - scoring 80 goals vs. a league average of 60. The next season, MacInnis misses the whole year and Pronger is the team's #1 quarterback. The Blues score 61 goals on the powerplay vs. a league average of 57: barely above average. The Oilers with Pronger as #1 PP quarterback were also barely above average on the powerplay, scoring 88 goals vs. a league average of 85. There are really three seasons in Pronger's career in which he has been his team's best powerplay quarterback, and in only one of them (last year in Philly) was the team significantly above average in PP efficiency. I'm not sure what happened last year in Philly. Maybe Pronger played great on the PP? But the two seasons prior to that when he carried the load, his teams were quite average in that department.
I am not here to tell you that Chris Pronger can't quarterback a powerplay. He handles and distributes the puck well, though he is not elite in either area, and although he has a big shot, it is too slow to be of much value on the man advantage. The numbers presented by overpass, without context, make Pronger look like an elite powerplay quarterback, only a touch below Lidstrom...but the truth is something else, and I think anyone who has seen him knows it. In an ATD sense, he is certainly not a good #1 powerplay quarterback.
I'm not trying to pick on you, overpass - this was just the best example of "statistical smoke" (to use GBC's old saw) I could think of off the top of my head. There are many more examples of such obfuscatory statistics in the player bios, not to mention a great volume of fluffy text (again, not specifically targeting overpass here). We really need to approach statistics in as sober and balanced a manner as possible, and make specific distinctions when they are known.
