I disagree with speed. Honestly, how often recently have we seen Gaborik use his speed to score a goal? In his first season here, that was a common occurrence, but not as much now.
Most of the goals that Gaborik has been scoring for this season and last are based on his intelligence. He's been scoring a lot of goals right below the hash marks, tips, deflections. Lots and lots of garbage goals.
Look at the breakaway OT goal on Rask. He didn't snipe it past Rask, he made an amazing second effort to bat it out of the air.
I really can't remember the last time Gaborik flat out BLASTED a wrist shot past an opposing goal tender. But Gaborik is smart enough to overcome his waining physical attributes because he is sneaky and smart.
I don't expect 40 goal pace after his contract ends, but I think 30 is reasonable. Also, he is a proficient passer. He will usually have 30-40 assists a season.
Edit: I think Gaborik is realizing how his speed is starting to slow deteriorate, I think that's why we only see a few quick bursts from him a game. He wants to preserve his legs and his quick burst.
Edit 2: What Levitate said too.
