The AFC West side, who had the worst record in the NFL last year, are unbeaten after their first four games of 2013.
The Tennessee Titans quarterback told reporters: "I think, defensively, they've had the talent for a long time and know they're really playing up to their potential.
"It's a team I'm familiar with in terms of the guys they have over there. I've played the Chiefs a bunch. The scheme is of the Jets family with some of the stuff they do, but a really fast, physical defense."
