What Seattle said was, 'We want you to be a part of this team. We want you to contribute. We know what you can do, and we're excited about it.' They wanted to put me on a flight that night," Jackson told me Sunday while flying to Seattle with his wife and youngest daughter.
"New England wanted to wait a couple days. I wanted to go where I was wanted the most, and that was Seattle."
New England can be a risky place for veterans, and especially running backs, to sign. Bill Belichick churns his roster and hasn't committed to a backfield depth chart for years.
Jackson conceivably could have rushed for 100 yards in Week Four and gotten cut in Week Six. The Patriots signed future Hall of Fame receiver Reggie Wayne three weeks ago and cut him already.
"What played in the back of my mind is how much New England turns over its roster," Jackson said. "That has worked well for them, and you can't blame them. But, at the same time, you want to be comfortable where you are.

I don't know if I'd go that far. Sure there can be a bit of churn but the players who got the system and who pan out will stay and the guys who won't, don't. It's not like we just use guys on a whim and then throw them away when done...
