Parker certainly has the better resume in comparison to Smith, but lets be honest, Tim Duncan deserves a lot of credit for those accomplishments made by Parker. Smith's defensive stats are impressive, but they are certainly not empty, Smith is a very good defender. Parker is underrated, but George Hill is the increasingly better defensive player. And this trade makes a lot of sense because a back court of Parker and Joe Johnson sounds scary enough to be very good and Josh Smith is locked up long term and is still very young, younger than almost all of the current free agents and better than a good amount of them.
