I'm going with Cory as backup PG, Mills as 3rd string PG and De Colo playing SG.
Now, Spurs have been linked for a month with 4 PGs (Bobby Brown, Royal Ivey, Sebastian Telfair and Mike Bibby). What does it mean?
Have Spurs some doubts about Joseph and has he Canada NT play erases these doubt?
Could Mills be traded away and Spurs would be looking as an experienced 3rd string PG?
Personally, I'm a big Joseph believer and I think he will be at the end of next season a damn good backup PG.
