Daley works only as a point of comparison- e.g. for a trade that most people on this board absolutely hated when it went down because they didn't realize how well Daley would fit in here. I don't think anyone is seriously saying that Daley and Gudbranson are the same, just that Gudbranson's showing more offensive and defensive instincts here, better mobility, than he did in Vancouver.
Plus, historical footnote, Daley had 6 points for the Hawks the year they traded him and was just flat out awful for the firs 1/3 of the season. He was objectively worse on that squad than Gudbranson was for Vancouver.
He was the big trade that didn't pan out for them.
