I don't think he will at all simply for the fact that if he remains healthy I think you will see his goals even out once again. Right now he is playing to his strengths and that is playmaking. After he gets his groove back and has a full summer and training camp with no injuries, I think you will see the goals and assists even out a bit more even if it is like his first or second stats.
Hitting a 75-80 mark would not shock me in any shape or form from Sid if he is healthy next season. But to hit 100 assists it depends a lot more on him, some good luck/bounces on line mates shots and none of his paired line mates going to lengthy cold spells. There are just a lot of variables outside of Sids skill/play that would have to align for him to hit 100 assists, is it out of the realm of possibility? No, it could very well be done. Is it a foreseen likely hood? Id say more unlikely than likely, but a full 82 game healthy Sid can do a lot of unlikely things.
So we shall see...
"No! forget the glass Woodhouse, just give me the pitcher, for I am a sinner in the hands of an angry god. Bloody Mary full of vodka, blessed are you among cocktails. Pray for me now and at the hour of my death... which I hope is soon. Amen."
Yeah, no I don't see him or anyone approaching that. 100 points is a HUGE accomplishment these days. Hell, Geno might (probably) will be the only one to do it this year. Sedin was the only one last year. Sid is great, but 100 assists is just crazy.
I doubt anyone hits 100 assists again, but if any current player can do it, it's Sid. He'd need to be healthy for 82 games, and his line and the PP would need to be ridiculous.
The powerplay, especially. Just look at Sid's career totals. His career high 84 assists came when he had a ridiculous 48 powerplay assists. His assist totals the last two seasons (he was on pace for "only" 68 last year) are far below that career high, largely due to his lack of PP assists (21 two years ago, on pace for 18 last year).
