Griffin said that Smith's ability means that the Titans should not prepare for the game as if he was a rookie quarterback, but treat him with as much respect as any other.
"Just watching film, they throw the deep ball more [than last year]," Griffin told the club's official website.
"Geno Smith is growing in confidence with each game. He's going to try to test us. We can't look at him as a rookie quarterback. There's a reason they went with him as a starter."
Smith has thrown for 801 yards in the Jets' opening three games of the season.
