Seahawks trying to cross off major needs

A defensive assistant coach scheduled to face Seattle this season told me during training camp he hoped the Seahawks would not acquire Marshawn Lynch.

The thinking was that Lynch would give the Seahawks' running game a needed edge.

The price Seattle paid for Lynch remains a key variable in determining whether this trade was a wise move.

Buffalo receives a 2011 fourth-round draft choice and an undisclosed 2012 choice. The value of that second choice matters a great deal. If it's a conditional pick, Lynch would have to perform well for the price to increase.

The Bills played the Lynch situation right by waiting until well into the season before making a move. The rest of the league knew Lynch was expendable once Buffalo drafted C.J. Spiller, but Lynch still had value. There was no reason for the Bills to give him away at a discount. Seattle was interested all along and that interest had to grow once it became clear the Seahawks' running game needed a boost.

The Seahawks have long-term needs throughout their roster. Acquiring Lynch could fill an obvious need at running back. From that standpoint, this move looks like Seattle trying to cross off a significant need so it can focus on filling others at quarterback, receiver, along the offensive line and elsewhere. There's a risk Lynch will not produce, but that's a risk associated with any player.
