UFA C's I consider more appealing than Glendening:
John Tavares
Joe Thornton
Paul Stastny
Henrik Sedin
Tyler Bozak
Riley Nash
Valtteri Filppula
Derek Ryan
Tomas Plekanec
Mark Letestu
Daniel Winnik
So you can immediately throw out Tavares, Sedin, Filppula and Ryan. A bunch of those guys are not 4th line centres so throw them out. What have you got left:
Riley Nash
Mark Letestu
Daniel Winnik
Winnik is more of a winger at this point and when he does take faceoffs he is well below 50%.
Riley Nash is close to 50% on the faceoffs and produces more offense but who says Boston doesnt resign him.
Letestu has similar numbers to Glen but Glen is better at faceoffs. Letestu is a good bottom 2nd so I cannot argue that one except because he bring a lot like Glen he will be in demand.
