I would move Franson before moving Kulemin. I think we'll ultimately see Phaneuf, Gunnarson, and Ranger as being better than Franson defensively, with maybe guys like Gardiner, Rielly, Granberg, Percy, and Finn being better than Franson defensively as well in the coming years.
And then I think from an offensive standpoint from the blueline, we're perfectly set shortterm (Phaneuf, Gardiner, Liles, etc) and longterm (Rielly) that we ultimately wouldnt miss him much.
Kulemin on the otherhand is one of our most versatile forwards, key to the PK, key to defensive play at ES, adds secondary scoring, and will ultimatly probably have a lower caphit in a few years than Franson.
