1) That first line has the potential to be dominant. It may take some time, but you have 2 elite talents there.
2) That third line is going to score. JV and Leivo out up goals in the mid teens last year which is not bad for a 3rd line. You might have questions about Sutter but he has put up numbers in the past.
3) That is fair. I think Tanev/Benn can act as a defacto shut down pair in some circumstances
