I don't know but I am delighted they insisted on being on the same team and ended up in Vancouver because Smith would have drafted Brendl even if one of the Sedins was available and that would've made the suckitude of the pick even greater.
This is the kind of question that the answer depends on who they are playing with. If Henrik is making perfect pass to someone who can't put the puck in the net it will make a huge difference. If he was to be passing the puck to Kovalchuk, Perry, etc his scoring would probably stay the same or go up.
As long as they're still playing with good players there shouldn't be much of a change at all in points.
Give Daniel a solid playmaker like Thornton, Spezza, ect. and the point totals stay the same I imagine.
Give Henrik a solid goal scorer like Kessel, Iginla, ect. and the same happens for Henrik.
But them in a similar situation (ie. Rangers for Henrik) and they will continue to produce similar numbers, put them in a better situation (ie. Pitts for Daniel) and the numbers will be better, and put them in a worse situation (ie. Columbus) they will produce less.
