Whos said anything about mailing it in, in the post you quoted? Safer to say that the guy loves money, hockey is simply means to end. He is a Jedi now is he?
Also past his prime years, like Malkin & Crosby who put up several 100+point seasons in their 20s and now is at 31/30, injuries has taken toll and still ppg players but not 100pt+ guys anymore.
And Radulov put up 18g 54pts as 30 yr old...so that is likely what to expect, not a game breaking or even all-star calibre player.
Dallas overpaid and will regret contract is my guess.
