There are better options out there then Kane for sure. That's something that Murray could probably do if he wanted to but he would take it back to the leadership group before any kind of move was made.
Again I look at a guy like Kassian that might be able to come in and play a similar, maybe more physical role and less skilled but still a guy that has a lot of room to grow. He's not the best example of a guy that has succeeded thus far but a guy where you see potential, been put is some pretty crappy spots even if they seem like can't miss (playing with the Sedin's), and a guy that really needs a specific role to succeed. In Otttawa, if they move Chris Neil that spot, role, and that position... that's exactly where you want Kassian and exactly what this team needs.
If by chance Kassian turns into a 20 goal guy (and the potential is 100% there) than you have a guy capable of scoring 15 every year, taking 100 PIMs, and really giving the Sens a much more physical and tough identity. He's also a guy you could potentially have for a decade.
Anyways, we'll see what happens but that's the player that's on the outs, having a tough time, and shutting his yap about it. He's a little nuts but most of those guys are and with some maturity and again the right role he would be a huge asset to the Sens.
