McDonough has had his share of ups and downs as a General Manager. However, even McDonough’s bad moves (drafting Alex Len and trading for and and signing Brandon Knight, for example) really aren’t the worst things a general manager has power to do.
There have been far worse general managers in the NBA, and while the Suns are nowhere close to competing for a championship, the Suns are definitely heading in the right direction. The downs, as mentioned above, are nowhere near as important as some of the ups.
The trade for Bledsoe early in his tenure gave us a starting point guard for years, who at some point will most likely be flipped for a valuable asset.
