Ok, first off, let me say, that the following cannot and will not ever happen......it is just a Texas-sized pipe dream
Spurs sign Leonard to max contract (can and will happen)
Spurs trade Splitter, 2016 1st, 2017 2nd, and 2019 2nd to Memphis for Marc Gasol (Grizzlies get something instead of nothing)
Spurs sign Joseph and Bonner, then trade both to Toronto for 2016 and 2017 2nd. (Toronto gets a very good backup PG and a 3 pt threat)
Spurs sign LaMarcus Aldridge to a 2 year deal (short contract because of the huge cap number in a few years)
Spurs sign Danny Green to MLE (gives time to work out long term deal)
Spurs sign Duncan, Manu, Diaw, and Baynes to vet minimums
Spurs trade 2015 1st to Minnesota for both of Minnesota's 2015 2nds
Spurs let Ayres, Williams, and Belinelli (can't afford to keep him) walk
Draft
31 - C Robert Upshaw - Washington (knucklehead, great shot blocker, lots of untapped talent but needs the right situation)
36 - SF Anthony Brown - Stanford (high IQ, very good spot up shooter, versatile defender)
55 - G Pat Connaughton - ND (high IQ, very good athlete, great court vision and awareness, decent shooter (Chip will fix his flaws), high energy defender)
Roster
PG - Parker, Mills, Anderson
SG - Green, Manu, Connaughton
SF - Leonard, Anderson, Brown
PF - Aldridge, Duncan, Diaw
C - Gasol, Baynes, Upshaw
Reality.....
we keep Leonard, Duncan, Manu, Baynes, Diaw
we lose Green, Belinelli, Joseph, Bonner, Ayres, Williams
we sign Aldridge, low-cost veteran wing player or two
we draft a big and wing with our 2 picks
