PITTSBURGH -- The Pittsburgh Steelers watched the Ladarius Green experiment fall apart in 2016 and didn't like the consistency of the Jesse James-Xavier Grimble-David Johnson battery in camp.
They were "not consistently varsity enough," as Mike Tomlin would classified it Tuesday.
The acquisition of former 49er Vance McDonald -- whom Tomlin calls an "NFL-caliber tight end" -- puts the team's current tight ends on notice, though that doesn't mean they can't all co-exist.
"We're not going to anoint him in any way," Tomlin said of McDonald.
