49ers' K'Waun Williams describes challenge of covering George Kittle


What makes 49ers All-Pro tight end George Kittle a nightmare for defensive coordinators are the dilemmas he creates.

He has the size and strength to block defensive ends. Linebackers cannot keep up with him in the passing game. And he can physically overwhelm most defensive backs.

K’Waun Williams, who has established himself as one of the top nickelbacks in the league, knows what it’s like to go up against Kittle in the slot on the 49ers practice field.

“You just got to be disciplined from the start of the down to the end, because he’s real crafty, strong, and he’s just relentless in everything he does,” Williams said. “He’s willing to block in the run game.

"So you just got to be on you’re ‘A game’ going against a guy like that.”
