Adding Zach Miller rare luxury for Seattle

RENTON, Wash. -- It's tough getting younger and better in unrestricted free agency.

The Seattle Seahawks' deal with Oakland Raiders tight end Zach Miller allows them to do both. Miller, 25, has 126 receptions and eight touchdowns over the past two seasons. He counts as a luxury signing, in my view, because the team already has a young option at the position in 27-year-old John Carlson, who appears to be a good fit for Seattle's offense.

Miller's ties to Seahawks assistant head coach/offensive line coach Tom Cable gave Seattle confidence the team was making a sound investment. Cable was the Raiders' head coach before coming to the Seahawks this offseason. Miller went to the Pro Bowl last season.

The Seahawks confirmed the agreement. Carlson is entering the final year of his contract, raising questions about whether the team would consider trading him before losing him in free agency. Cameron Morrah and Anthony McCoy are also young tight ends on the roster.
