Extending Green would weaken our tank for Jack Hughes pretty good though... if Green doesn't resign I think 55 year-old Kronwall might be running the point on the PP1 ..
He's been on the first unit for the past two seasons , Green for the most part has been on the second unit, though they have split the time pretty even and Green gets 5 on 3/ 4 on 3 type situations, so he ends up with more overall pp time.
I don't want to see Kronwall on the pp at all next season, just wasted minutes, give it to two younger players if Green signs elsewhere.
