Brandon Marshall an Option for Seahawks?

Marshall (6'4, 229) put up 2,290 yards and 17 touchdowns over the last two seasons with the New York Jets, playing in 31 games, and now is a large wide receiver option for 31 other teams. Marshall turns 33 later this month, however, and may run a steep cost for his size and over 12,000 yards over 11 year career. Despite the age, price, and numerous outbursts over the years, is Marshall worth bringing to the Seahawks?
