Antoine Winfield and Nnamdi Asomugha have joined the NFC West recently as high-profile veteran cornerbacks.The one-year contracts they signed show the Seattle Seahawks are betting bigger on Winfield than the San Francisco 49ers are betting on Asomugha.That makes sense given that Winfield, by all accounts, has played at a higher level recently.Asomugha is getting no guaranteed money. He can receive $1 million in base salary, plus a $25,000 workout bonus, plus a $225,000 bonus if he remains on the 53-man roster for the first game of the regular season (at which point the $1 million salary would become guaranteed).
