The Spurs as currently constructed are flawed. Pop had faith in 5 players in the playoffs, Duncan/Ginobili/Jackson/Parker/Leonard. Clearly the Spurs suck at attracting free agents. So, most upgrades need to come via the draft and trades.
Most posters on this site believe that Parker is a top 5 pg. Even top 2. Well, if Deron Williams can net 2 1st rd picks, Derrick Favors(#3 overall pick), and Devin Harris, then Parker should net a starter and draft pick. I'd have traded him to the Trailblazers before the draft for the #6 and #11 and drafted Harrison Barnes and Royce White. That way the Spurs get 2 players for 1 and cap space of about $8 million.
Point guard is the easiest position to replace in the NBA. The last 3 champion point guards are ... Mario Chalmers, a 38 yr old Jason Kidd, and Derek Fisher. The Spurs would have had a choice of Dragic, Nash, Lin, or Miller. But, again the Spurs suck at attracting free agents, so we'd wind up with Jameer Nelson for $5 mil/yr.
So, basically the team would be: starters; pg - jameer nelson($5 mil), sg - Kawhi Leonard($1.8), sf - Stephen Jackson($10), pf - Anthony Randolph($4), c - Tim Duncan($12), 2nd 5 - pg - Manu Ginobili($14), sg - Danny Green($3), sf - Harrison Barnes($2.5), pf - Royce White($1.7), c - Tiago Splitter($3.6), bench - Neal(.8), Bonner(3.6), Joseph(1.2)
Why Harrison Barnes? To replace Stephen Jackson should he leave after this year. Why Royce White? I see him as the kind of revolutionary positional player that Edg5 wrote insightfully about. I literally see him as a point power forward to bring the ball up the court. Screw a backup point guard. Let him run the pick and roll with Ginobili as the screener. A switch let's him at 6'8" 260 lbs with a 7'0" wingspan back down a point guard for a layup or draw double teams for easy 3 ptr's!!!
So, yes, I moved Ginobili to back up point guard. And yes, I made Leonard the starting 2 guard. The Spurs would be younger, longer, more athletic, and more importantly - versatile. Randolph/White aren't one-dimensional ala Bonner/Blair at the 4. I'd like to see this type of team compete for a championship without getting unathletic, out of shape, European only tested, or old past their prime bargain bin types.
All it took was trading Tony Parker before the draft.
