Usually you will always be bad in one category which is hitting in your case so don't worry about that stat
You are getting overall better stats with this trade. You will be missing out on is goals a bit but you're getting Assists/Points/Faceoffs/Shots/SHP/PP points with these two players. Toews/Datsyuk are very consistent players, which is huge in fantasy.
Toews/Datsyuk both on first line PP/PK which is also great for you.
Take the trade, hopefully it's still available for you
