It's just insane the talent in the system+on the team. This team has dynastic potential. Assuming we can find a Hainsey replacement, picture this;
Dermott - Liljegren -> Dermott is steady, lets Liljegren play his offence and teaches him gap control and I think Liljegren has legitimate high end upside (60-70 points, similar to Burns offensive upside but more stylish). Mobile unit.
Rielly - Hainsey/Hainsey replacement -> Primary or secondary minute crunching pairing. Seen how well it works with 23 year old Rielly. Imagine a 25 year old Rielly.
Borgman - Zaitsev -> Zaitsev being more mobile and offensively talented. Good size and grit bottom pairing and allows for the team to roll a decent bottom pairing that isn't dead weight. Add this mobile, offensively talented blue line to Matthews, Marner, Nylander, Kapanen and JVR (if he's signed to a decent cap hit)? We're going to be stupid good.
