Exactly. Don't get too enamored with the shiny new toy. Namestnikov did squat while in New York and wasn't much better in Ottawa. A lot of that may have been due to usage, but I'm not so sure he's a better player than Donskoi. Donk was playing otherworldly to start the season before he cooled off and then got hurt, he's still a very capable contributor. He, like Namestnikov, is a complementary player who needs talent around him in order to succeed.
The question really shouldn't be a choice between Namestnikov or Donskoi. It should be Namestnikov or Compher. And frankly, if you can get Namestnikov signed for a similar contract, I'd be okay with them moving JTC.
