Fantastic deal IMO.
Why is this a bargain for a player that hits around 50 points a season?
1) Proven track record of making players beside him better. Bouma got a nice raise (and his highest goal totals in his entire career, probably all the way down to midget). Colborne got a hefty increase playing next to Backlund. Tkachuk is good, and that relationship seems to be symbiotic there, but I argue that playing next to Backlund was a perfect way to enter the NHL. Bennett has looked impressive with Backlund. The list goes on... He makes players around him better.
2) Look at those defensive starts. Look at that quality of competition. Compare that around the NHL, and let me know who in the world gets that buried but still produces at anything close to that level.
3) From point two, he gets the heavy defensive zone starts. That makes it a lot easier for Monahan's and Jankowski's line to go out there and generate some offence. Those two other lines really are huge beneficiaries of having Backlund being buried every night.
He is an advanced stats darling. Possession monster. Great teammate. He still puts up good numbers. He was 4th in voting last year for the Selke,and no, he is not way off from Kopitar and Kesler defensively. Bergeron? Yeah, Bergeron is the league's best defensive player (though he doesn't get buried like Backlund does - but nobody seems to). Backlund is right up there.
So yes, this is a bargain contract. In fact, I will argue that strong defensive players take longer to develop, and are in their 'prime' at a much later time in their careers. Bergeron was always an effective defensive player, but who is going to argue he was remotely THIS good defensively
@25? Or Kesler? Or Kopitar? These guys hit their prime around 30 for the most part defensively, and stay effective until they can no longer skate. Backlund is a fitness freak (as mentioned by Treliving) and I don't worry about year 5 or 6. His production might be down a bit, but his defensive acumen will probably be the sharpest and he will probably be an effective defensive specialist at age 34.
