I hope you're right..... Insofar as his understanding that he needs the help, even if it leads to a reduced role.
But I've also heard a lot of Kings fans talking about how Fox said all that stuff about wanting help, and sharing the ball, yet played really poorly when Haliburton came into the team, and wasn't a willing distributor/liked sharing the ball-handling duties. Even though it's typical to bad-mouth the star leaving town, I was surprised to see it seemed like a commonly-held view amongst Sacto fans at the time - and certainly shared, on some level, by the Kings FO in order to even green-light the Sabonis trade.
I'm looking forward to next season and seeing the dynamics play out on the court. Winning cures everything, as they say, and hopefully the Spurs can get on with that.
