I don't like the term, and it's risky with McCabe not being Montour/Forsling, but people do realize that OEL spent more total minutes with one of those 2 in the top 4 than he did with Kulikov on the bottom pair right? And that both he and the Panthers did more than fine with him in those minutes?
He's literally coming off a season as a 4/5 for a 110 point cup winning team, where he saw a lot of tough minutes. Now, there's no guarantee he can do that for 82, or see the same success with the Leafs personnel instead of Florida, but:
A- if he was a slamdunk he wouldn't have signed for 3.5
B- the whole "he only rebounded as a pure bottom pair, extremely sheltered 6" is objectively wrong
