Richard Sherman made a statement with his deflection that sealed the victory.

And then he kept talking and talking and talking.

Sherman, the mouthy All-Pro cornerback, took aim at 49ers wide receiver Michael Crabtree in the immediate aftermath of the Seattle Seahawks’ 23-17 victory in the NFC Championship game.

“I’m the best corner in the game,” Sherman shouted during his postgame interview with FOX’s Erin Andrews, “when you try me with a sorry receiver like Crabtree, that’s the result you’re going to get.”

Trailing 23-17 with 30 seconds remaining, 49ers quarterback Colin Kaepernick said he liked the matchup of Crabtree facing single coverage on the outside against Sherman.

Kaepernick lofted the pass toward Crabtree in the back right corner of the end zone. Sherman made a leaping deflection and linebacker Malcolm Smith recorded the interception to clinch the victory.

“I really appreciate that, Kap,” said Sherman, a third-year player from Stanford, where he played under 49ers coach Jim Harbaugh. “You try me like that. I hadn’t gotten many opportunities all game. I’m happy. I’m happy about that.”
