No point doing this unless Walker comes with an extension. Even then I don't think it makes sense to trade Niemela.

Why would leafs do this?

Flyers have no real use for Timmins, but the value is right imo. Replace him with like a 3rd

Massive overpay. Walker had a decent start to the season but he's really just a soon to be 30 year old bottom pair defenceman. Niemela will be better, Timmins is different but more effective offensively and bigger. And Robertson is a good young player who deserves more ice time. This is a waste of assets

niemela/timmins don't have much value to philly with amount of d they have that can play right side

drysdale/bonk/attard/zamula/andrae all have edge on niemela in terms of potential

I would say no. Timmons has no value to Philly. Apparently we aren't interested in Robertson, which does make sense we have plenty of undersized wingers. Niemela isn't a bad piece, but as everyone else has mentioned we have a ton of 3rd pair defenseman in the pipeline. DannyB wants picks or young centers with upside.

What about Grans, he got a future with the Flyers or has his stock dropped?

didn't even cross my mind, he's played well on horrific ahl team. he's another one that would be close to niemela
