Ryan Fitzpatrick has said that the Kansas City Chiefs have been "playing up to their potential" so far this season.
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."
Fitzpatrick will be the Titans' starter against the Chiefs this weekend while Jake Locker recovers from a hip sprain.
