This whole having a puck digger on your line theary is so generalized. It doesn't need to ALWAYS be the case.
Zetterberg - Datsyuk - Hull
^ one of the best and popular NHL line in history that WORKED.
lol that line worked great because you had 2 puck possession kings with D and Z. And then one of the top 5 goal scorers in NHL history to dish the puck to. I don't think its a particularly great example to use
