I'll grant that no front office can know exactly where the team will draft a year in advance, nor will they know exactly who will be on the board a year in advance. I us the phrase "hindsight is 20/20" as much as anybody else.
I will direct posters to the first few pages of the Sexton thread. This is not a case of hindsight when a thread reveals actual foresight in real time. I can tell you that a point guard under 6'2 is available in the top eight every year while a good match for a 6'2 shooting guard is rarely available.
My first post in the Sexton thread was for dozens of people to give the pick a shot to work out. That's how many people saw the drawback of beginning a rebuild with a shooting guard in a point guard's body.
I do like Sexton's work ethic. He is a good NBA caliber player. Both of those statements can be equally true to the statement "It's hard to build a young team around Collin Sexton and he would be a smart trade target for a contender, if they are willing to pay fair compensation."
