Hello Enapai:
You need to get Dobber\'s 2007 Fantasy Prospect Report.
Dobber has compared Berglund to Sundin with an upside of 35g, 50a.
He has compared Hensick to Steve Sullivan with the same upside, 35g,50a.
One of the key differences for you might be that Hensick has a chance to make the Colorado team this year whereas Berglund will not be here until next year, at the earliest.
Again buddy, you need to get Dobber\'s Reports. They will help you a ton.
