After spending all seven years of his NFL career with the San Francisco 49ers, tight end Delanie Walker knew change was inevitable.

But he admits joining a new team to take over the lead role at the position has felt weird.

“It’s like you’re getting a divorce,” Walker said with a chuckle. “And now you get a new wife. You gotta learn all over again. You are on your best behavior.”

Walker joining the Titans via free agency was a match not made in heaven, but rather by circumstance. After playing in the shadow of Pro Bowl tight end Vernon Davis, Walker wanted to be the lead man at tight end. Having lost former tight end Jared Cook to the St. Louis Rams through free agency, the Titans needed a lead dance partner at the position.

Thus, the marriage between Walker and the Titans when he signed March 14.

“When I was with the Niners, I played 70 percent of the time,” said Walker, who had 21 catches for a career-high 244 yards and three touchdowns last season. “Being here and having the ability to play 100 percent of the time, I think I fit into that role.”

Which is being one of several offensive weapons at the disposal of third-year quarterback Jake Locker. That’s fine with Walker, who has been used primarily as a blocker but has seen his production gradually increase, especially last season when his average of 16.4 yards per catch led all NFL tight ends. He had three catches for 48 yards in the Super Bowl.
