If we are to keep 2 of Oduya, Leddy, and Clendening to have a puck mover on each d-pair (Keith is obviously on the top pairing), I would move Clendening. His stock is relatively high and I just see Leddy being a better complete player (now and once he has fully matured) than Clendening is now and may ever be. And although Oduya is the player (besides Bickell) who gives me fits game in and game out (makes errant passes, rarely wins board battles, can't clear the zone), there is something to be said about the Swede connection with Hjalmarsson that maybe has contributed to Hammer finally maturing into a solid defender for us. So of blueliners, Clendening is our biggest bargaining chip IMHO.
For forwards, assuming Teravainen is our 2LC whether by season's end, next year, or the year after, then Pirri is our biggest bargaining chip as far as forward prospects go. Given his skill set and given that Toews has 1LC locked up pretty much until he retires, it's 2LC or bust for Pirri. I don't think he would thrive at all as a checking center. With that said, if Teravainen is at 2LC, Pirri has no spot. I like Pirri a lot and hope he would make the starting roster in the near future, but I just don't see it happening due to whatever qualms Q has with him.
Morin is also a bargaining chip.
