Oilers are trying to be the leafs when they should be trying to be Pittsburgh.
Crosby-Malkin-Staal
McDavid-Drai-RNH
Pittsburgh stopped doing that a long long time ago. They went to
Crosby
Malkin
Staal
so what the OP is suggesting is what Pittsburgh did and has been doing for years now only insert a different centre for Staal as he wanted a trade to play in the top 6, he wasn't happy playing 3c and given RNH is a UFA at the end of the year and probably walking, what the OP is suggesting emulates Pittsburgh even more.
