Greene may start out his partner, but I think they know that they shouldn't be relying on Greene to play 20 minutes or more anymore. Especially not in a year where he's 37 years old and in what will more than likely be his final NHL season. And if he's playing with Subban, he'll be playing over 20 minutes on most nights.
I think with the way he was used late in the year, Severson might be his partner. They loaded him up with the minutes late in the year and he did pretty well.
I'm sure after the first goal they're on the ice for, people will complain that we needed a ''Defensive defenseman'' or ''Defensive specialist'' instead of Subban.
