Rango wasn't going to do this in NJ, he was stuck in the bottom 6 and there wasn't a way out for him. Stop whining about a player that outlived his usefulness to the team.
He didn't need to do this in NJ, If Toffoli wasn't here it would have made the entire team more versatile in the way it could be moved around. So say Ruff stuck him in the bottom 6 and never gave him a shot in the top 6, fine, he was a fine player down there that wasn't ever a liability and actually could contribute down there, Toffoli couldn't. He could be used on the PK, Toffoli couldn't.
But say he was given another go in the top 6, are there any goals you can point to this year that Toffoli scored, that Shara wouldn't have? If given enough rope, you can even make the argument that with his somewhat better speed and willingness to get into dirtier areas, he could have done better.
No way to say for sure, but to say with 100% certainty that he wouldn't be good here is crazy and just trying to defend something for the sake of it.
