The Spurs FO should have really traded #26 for two picks in the 2nd, then traded the other two 2nd's for a better pick in the upper part of the 2nd, then traded the 3 high 2nd round picks for a crappy team's #1 next year, then bought a late first rounder with the $3M in tax receipts from last season, then traded next year's #1 and the Matt Bonner for two mid-to-late 2nd rounders and traded the banked #1 from the crappy team for a pick somewhere around #26 in the first round.
And really, the Spurs should have aggressively pursued the best available FA who might have been willing to take the MLE and offered that entire MLE to him as the very best offer that the Spurs could make.
If that failed, the Spurs should have thrown ridiculous contracts at restricted free agents who were going to be matched even though they aren't actually worth those contracts, just to be sure to make a big splash in free agency.
Then everyone could have at least been happy.
