Very true, he is no Grunfeld, he is a competent GM who won four division titles based on tanking for #1 overall draft picks and spending huge amounts of money. He is not an elite GM.
Good point on the international signings. I'd need to see a comparison of team by team, but Soto and Robles are a great starting point.
I think he just inherited very little rather than tanking. He needs postseason success to be considered a top GM.
