Over the last few seasons, it's been written and said on numerous occasions that the Vancouver Canucks needed to be a bit tougher to play against if they wanted to lift that elusive Stanley Cup over their collective head.
It's also been written and said on numerous occasions over the last few seasons that the defensive structure of the New York Rangers was holding back the likes of Brad Richards, Chris Kreider and even Rick Nash.
With the Rangers and Canucks swapping coaches, we'll be able to see whether or not these points were accurate or not.
John Tortorella will likely try to bring at least a bit of his defensive structure to a team that is used to wheeling and cycling freely. Will Vancouver be better off under Torts, who will demand accountability from players that haven't been grilled much over the last few seasons?
The exact opposite question is now an intriguing one for New York.
Can the players that were allegedly held down by a shot-blocking system up the ante and increase their fire power under the offensive-minded Alain Vigneault?
We'll know by the midpoint of the season how the Freaky Friday-esque coaching swap is working out, but one thing is clear: neither the Rangers nor Canucks will have an excuse to fall back on if these coaching changes don't pan out.
After years of blaming shortcomings and disappointments on the guys behind the bench, it's now up to the players to prove that it was the systems and not themselves that led to consistent downfalls.
