Everyone moving one of the Kostitsyn best include both because I have a suspicious feeling the other will perform poorly because of a dislike of no longer having his brother around, viewing it as distasteful. Nonetheless while I am still on the fence about Andrei, I would not trade him for San Jose's trash. Cheechoo? He has netted less points than Andrei and is I believe five years his senior.
This is a possibility I just thought up on the fly. So feel free to flame.
To Ottawa
Roman Hamrlik
Thomas Plekanec
Jonathan Cheechoo
To Montreal
Patrick Marleau
Christian Ehrhoff
To San Jose
Dany Heatley
Chris Kelly
Defensive prospect from Montreal not named Subban
Conditional draft pick (2nd unless Montreal passes into the 2nd round of the playoffs; at which time it becomes a 1st)
San Jose would likely have to offer something else to Ottawa, a draft pick perhaps and Ottawa still has some cap issues otherwise this sounds like a fair deal.
Ottawa improves on defense and adds to scorers, albeit taking a chance on Cheechoo (which is why I mentioned San Jose having to give them a draft pick.) Montreal has a huge improvement at centre, finally acquiring the big body centre they have always needed while upgrading significantly on Hamrlik and finally San Jose acquires one of the best goal scorer in the NHL and a defensive prospect with the possibility of another prospect depending how well Montreal fairs.
