To be Blount: Seattle's trade affects 49ers

The 49ers can blame the Seahawks for free-agent running back LeGarrette Blount's decision to sign with the Titans after agreeing to terms with the 49ers.

Seattle's move to acquire running back LenDale White from the Titans made the situation in Tennessee preferable to the one awaiting Blount in San Francisco, according to Aaron Wilson of National Football Post.

Blount's decision to change his mind also demonstrates the difference between "agreed to terms" and "signed" when it comes to NFL contracts. Had Blount signed with the 49ers, he would be pretty much stuck, unless the team agreed to release him. But because the Oregon running back had merely agreed to terms, he was free to change his mind.
