LONG POST ABOUT STATS AHEAD.
As you all should know, I'm a bit of a stat nerd. I'm not one who subscribes to the CORSI stuff, mind you - I prefer to look at what's most important: scoring.
I've used a metric known as Points Created now for over twenty years. It's basically points, plus plus/minus (DO NOT LAUGH), plus penalty minutes times the league PP/PIM constant (which is always negative). The constant is what is says on the tin: league PP goals divided by total league PIM. Put it all together, you have a player's point creation total.
As an example, there's HF's favorite son, Connor McDavid. He has 72 points, and a +20 rating with 22 PIM's (or at least he did as of Friday). The league constant is .064503*, so that translates into a PCR of 90.6.
Now, what I've been doing as of late, to put a better value on a player's performance (because a 90 PCR could be good in the modern NHL, but middle-of-the-pack in the NHL of the 1980's), is to convert that PCR total into a per-60-minutes total. This way, we can use that to come up with a hypothetical winning percentage using the old Pythagorean Theorem tossed about by Bill James (The idea that the square of goals scored is to the square of goals allowed as wins are to losses; in our case the league goals per game total is the goals allowed in the projected winning percentage).
For McDavid, his PCR is 4.009 (90.6 x 60/1355.73 TOI). Comparing that to the league average goals per game of 2.772105, we get an offensive winning percentage of .677.
NOW... you take that total, multiply back by total TOI, divide by 60, and you have 15.3 offensive wins. Subtract .677 from 1 and repeat, and we have a projected offensive won-lost total of 15.3-7.3 for McDavid.
To make that a single number, I use another Jamesian creation, Fibonacci Wins, that multiplies wins by winning percentage, then add wins and subtract losses. For our example, Connor has an OFIB of 18.32. Only one other player in the NHL (as of Friday) had an OFIB greater than that - Mikael Granlund of the Minnesota Wild, whose 14.2-5.5 offensive won-lost record turned into an 18.89 OFIB.
And that's where we come into our problem. We have exactly one, count 'em, ONE player for Nashville who is in the top 50 in OFIB (the cutoff for which, by the way, is 6.15). That is Viktor Arvidsson, with an 8.65 OFIB (56.8 PCR, 10.1-7.3).
Washington and Pittsburgh have 8 and 6 in the top 50, each. Four other teams have four in the top 50, and they're who you'd expect: Columbus, Chicago, Minnesota, and the NY Rangers.
Here's my point: we do not have the firepower to compete with teams who have four or more big stars in their lineups. All other things being equal, this team is toast as soon as we hit the playoffs, especially if we have to play either Chicago or Minnesota in the first round.
Obviously, top 50 players don't grow on trees. Columbus and Minnesota's appearance on the list suggests that it doesn't take much to get to that next level. But having only one player with that level of "potential wins" in them isn't going to help come playoff time.

* - The league constant has fluctuated since the Preds entered the league, varying from .0431 in 1999 to .0645 in 2006, and dropping down to .0511 in 2012. A good estimate is to divide PIM by 20, but doing it on a per-season basis normalizes the totals.
