Yes you can - Sweeney does not have one good NHL player acquisition that did not come through the draft. That was Keith Gretzky
So the GM has to take the fall for, what you deem, bad signings/trades, but he gets no credit for picking the players? Last time I checked, managements work as a unit, not a one man show. You want to blame Sweeney for the signings/trades? Fine... Go ahead, I don't agree with it, but that's neither here nor there. Blame everyone in the front office then. He has Neely above him, he has pro-scouts...Blame them as well, not just Sweeney.
And it goes the other way as well. You want to credit Keith Gretzky for all these picks? Give credit to Sweeney and the amateur scouts as well. This isn't a situation where 1 guy is in charge of X and 1 guy is in charge of Y. They work as a team.
Just like the players on the ice work as a team....
