Getting physical is not the answer for stopping Curry and if you're going to resort to dirty tactics, be prepared for an elbow to the temple to one of your superstars from one of the Warriors big men probably Bogut on a dirty screen.
Handchecking wouldn't solve anything either when you look at how great Reggie Miller was in the 90s, especially in the postseason, working off ball which Steph excels at. Its the fact that he's dominant with or without the ball in his hands that makes him difficult to scheme for.
