Out of curiosity what pairing did letang play in the 09 playoffs? 3rd right? His defensive acumen isn't held as spectacular even today, so doubt he was much better at it back then compared to where pouliot is now.
Don't really care who plays, pouliot or harrington, as neither will be the key difference in them losing a series or not.
IIRC
Gonchar Orpik
Gill Scuderi
Letang Eaton
One of Boucher/Sydor.
