I don't know about that. Podz may play somewhat similarly but the size Joshua brings makes him highly effective in that hard forechecking bottom 6 role. He's also very good on the PK.Joshua is the one guy that we have a built in replacement for. Podkolzin can slot in almost perfectly on paper into that spot in the lineup.
I think Joshua has played really well and earned himself an inflated contract elsewhere, but I also don't think he's an irreplaceable piece. He's in an absolutely perfect situation right now where he has two linemates that play with a lot of quickness and anticipation. Joshua just has to read of them and take his man, then his linemates help out from there. Joshua has gotten really good at it but I think we can find others who can do it as well.
Podz at this point has not really shown he can be an NHL player. Let alone an effective one. And I'll be honest I'm not at all hopeful that he is going to be an everyday NHLer.
