While this season was likely Antonio McDyess' last season in the NBA, it won't be Tim Duncan's last, according to Spurs coach Gregg Popovich.
As we have said in a few posts already, in order to sign someone significant this summer, Duncan would have to exercise his Early Termination Option, something RotoWorld says he may do to give the Spurs more flexibility.
Duncan is clearly past his prime at 35 years old, but with careful monitoring of his minutes he can still be a major factor in a push toward another championship. He can also opt out of his deal and/or restructure his contract this summer, likely to give San Antonio more flexibility, but there aren't any details to report.
While it's doubtful the Spurs will make major moves or move any of the core, Duncan's restructured contract could leave room for the Spurs to find help in the post and possibly some added depth at the small forward position.
