In theory, we could spend hours going over every one of his PP shifts since his career began, and you could see how getting a 12 second "shift" starting in the D zone is actually not representative of a real PP opportunity in terms of what PPP/60 might be understood to meaningfully show.
You could see how, when essentially all PP minutes accrued over a 3 year period are simply those 10-20 second nothings stacked up, the actual Power Play time is significantly less than actual seconds spent on the an advantage.
You might be led to notice how Filip Chytil and Kaapo Kakko are a few notches above Lafreniere on the list you attached. You could of course take the stat as fact and assume that all 3 are historically impotent PP producers, linked by cruel circumstance to be on the same PP2 unit.
Or you could ask yourself - is it that all 3 of these guys, whose PP shifts were almost exclusively shared over the period since Lafrenieres career began, are all historically poor PP producers? Or is it actually that they were all put together in the exact same situation over and over again - a token 15 seconds at the end of a 1:45 shift by one of the dominant power plays of the last 5 years, with no plan in place or expectation or trust in scoring ability. Just a token 15 second "PP shift" for the Kid line + Trouba and Barclay Goodrow, or Dryden Hunt, or Sammy Blais.
I watch the games. I watch the shifts. I have the context.
