Pete Carroll said the team thought it was time to give up on Christine Michael, the former second-rounder who was sent to Dallas for a conditional seventh-round pick.

“We spent a lot of time with him. We gave him plenty of opportunities. He’s a good, hard-working kid. … We just thought it was time.”

Carroll said Jackson offers much more experience and in the passing game, catching and blocking. “On this team at this time, it was just the way to go.”

Carroll said Jackson is a “good pass pro” guy and “he’s a terrific catcher. So that part is going to fit in really well.”

“We like Marshawn on third down, but he needs a break now and then,” Carroll said. “I like to have a real steady guy going in. Without Turbo available to us, he was the steady guy to go in. Christine wasn’t that guy to take that spot, and we didn’t want to put that on Thomas (Rawls) at this point.

“We think that’s going to be a good, solid move and get a real classy guy to add to the locker room.”
