Although Marchand is an all-time great penalty killer, the numbers don't really support him being an excellent defensive player at even strength. His analytics numbers for defense have mostly hovered around average.
Which, to be fair, is excellent for a player with his offensive abilities. Most guys who are consistently above 80% in offensive play driving metrics tend to be bottom of the barrel defensively. Managing to show up as average defensively means he's WELL above average, for a high scoring winger, but in the grand scheme of things, still average.
Give him a huge bonus for his otherworldly penalty killing record, and I still don't see how he's deserving of mention in this thread.
Chronologically, I'd name guys like Rusty Crawford, George Hay, Frank Finnigan, Baldy Northcott, Marty Pavelich, Nick Metz, Pulford, Armstrong, Marshall, Marcotte, Westfall, Ramsay, Gainey, Kurri, Tikkanen, Erixon, Lehtinen and Stone.
The fact that this was all I was able to come up with off the top of my head shows how most of the all-time defensive forward greats played center. I could name four times as many of them in the same amount of time.
