Through free agency, the Spurs have added Pau Gasol, Dwayne Dedmon, David Lee, and Patricio Garino. With the retirement of Tim Duncan this summer, and likely retirement of Manu Ginobili next summer, the off-season moves now seem poised to be extremely vital for the future of the franchise.
Also, all new signings apart from Garino have options to become free agents next summer, as well as contract expirations of Patty Mills and Jonathon Simmons in 2017. Luckily, though, the summer of 2017 is slated to host a number of top quality free agents of all positions, which bodes well for the Spurs.
