I've heard rumors and conjecture but I've never seen anything that resembles documented fact.
The Suns needed another point guard because it was unknown if Cam Payne would be a solid contributor outside of eight games in the bubble. Whether Haliburton was 2nd or 3rd on the depth charge was a decision for Monty. The point is Haliburton was the BPA at #10 and as a plus, he filled a position of need.
Jalen Smith was one of the physically less ready to play players in the draft. If James Jones wanted an immediate contributor he drafted the wrong player and I like Stix. His body is simply not ready for the NBA pounding.
I believe the Suns brass had complete faith in Payne and Carter. I didn't want Haliburton I wanted a PF. Now if they picked the wrong player that can be argued and played out next year. But to say Haliburton was BPA at 11 in a crap draft is not moving the needle for me
