Here's a better question: How many 20+ goal scorers?? I think we will have 7
I say 3, maybe 4. Tatar, Nyquist, and Zetterberg. Franzen has a shot if he can stay healthy.
We should have a number of guys around 15: Datsyuk, Abdelkader, Richards, Sheahan, Pulkkinen, Green, and Kronwall. Maybe Helm, if he can stay healthy.
Edit: I forgot Pulkkinen
