RENTON, Wash. (AP) — Thomas Rawls still smiles. He still talks of his determination and desire to help his team improve and ultimately win. But it hasn't been an easy first month of the season for the Seattle Seahawks running back. He's been in the middle of a backfield rotation that's proven more challenging to balance than first expected. Rawls has gone from being the presumptive starter before the season began, to being slowed by yet another injury, to suddenly being a healthy inactive last week when the Seahawks thumped the Colts. And now, he's back in a prominent role with perhaps a chance to claim his place again as Seattle's primary ball carrier.
