HOUSTON (AP) - Houston Texans All-Pro middle linebacker DeMeco Ryans likes the challenge of trying to decipher Peyton Manning's frantic calls and signals before every snap.
Ryans knows he won't understand much of it when Houston opens its season against Manning and the Indianapolis Colts on Sunday.
But if he can pick out one key phrase and relay it to Houston's defense in time to ruin a play, he'll feel like he's earned a minor victory against the four-time league MVP.
Manning has had his way with the Texans, throwing 37 touchdown passes and only eight interceptions while winning 15 of 16 career meetings.
The Texans can boast one area of success - they've sacked Manning 10 times in their eight games since 2006, the most by any team in that span.
