Coach Kyle Shanahan did not require much convincing that free-agent Jordan Reed could help the 49ers.

But, just to be sure, Shanahan recently reached out to left tackle Trent Williams, a teammate and close friend of Reed’s since in 2013, to seek his opinion.

The 49ers signed Reed to a one-year contract this week. He reunites with Williams, who came to the 49ers this offseason in a draft-day trade, and with Shanahan.

“Kyle obviously drafted Jordan, so I didn’t have to talk him into telling him how good of a player he was,” Williams said Thursday in a video call with Bay Area reporters. “I think that’s proven. That’s well-documented.

“I think I just gave him a little insight -- because Jordan is one of my closest friends -- into just how he was really feeling and where his mental state was.”

Reed’s first NFL season was Shanahan’s last season as Washington’s offensive coordinator under his father and head coach, Mike Shanahan.

Reed, 30, has been plagued by injuries, appearing in just 65 games during his seven seasons.

Reed has 329 career receptions for 3,371 yards and 24 touchdowns. His best season came in 2015, when he saw action in 14 games and caught 87 passes for 952 yards and 11 touchdowns.

 

He did not play last season after sustaining a concussion in a preseason game. It was his seventh documented concussion. Washington released him in February.

Reed joins a 49ers group of tight ends that includes All-Pro George Kittle, and Ross Dwelley, Daniel Helm, Charlie Woerner and Chase Harrell.

“I think he’s going to make this team just that much better,” Williams said of Reed.

Shanahan is certainly in agreement with Williams about what Reed can bring to the offense.

“Everyone is aware of Jordan’s ability,” Shanahan said. “When he’s been healthy, he’s played at an extremely high level. And he’s been one of the first third-down tight ends in the league when he’s been healthy.”
