As someone who didn't mind the trade at the time, he was hopefully going to bring something to the table to get us possibly a cup, I mean, he was a pretty standard deadline acquisition that happens with a lot of teams.
I can fully admit I was wrong about it, although I think he actually played well in that playoff run (and lots of people disagree I know.) Last year though? He was abysmal in every facet of the game.
As far as the "someone else would have stepped up" comment, seems weird, I guess you can say that about anything really if you want to dismiss something? Overall, acquiring players at the deadline doesn't seem worth it in the end, especially if the mentality is if you don't win the cup because of it, its a waste of a trade, because it probably will be.
