Stephen Curry has struggled in Games 3 and 4 of the Golden State Warriors' series against the Oklahoma City Thunder, not showing any of the explosion he had during his MVP season before injuring his knee.

"He's playing at 70 percent, at best," a source close to Curry said.

Curry has downplayed the injury in his comments to the media.

Privately, the Oklahoma City Thunder have seen how Curry doesn't have the ability to make the big men switching onto him pay a price.

Curry injured his ankle in Game 1 of the first round and then his knee when he returned in Game 4 slipping on a wet spot in Houston.
