The Pittsburgh Steelers like keeping four tight ends on their 53-man roster and they like to reach into their past to find players.
They may have done both yesterday by signing TE David Johnson to a one-year contract.
Johnson was a seventh-round draft pick by the team out of Arkansas State back in 2009 and played with the Steelers through the 2013 season.
He signed with the San Diego Chargers as a free agent in 2014 and played in 30 games (six starts) with two catches for eight yards the last two seasons. In his previous stint with the Steelers, the 6-2, 260-pounder caught 20 passes for 216 yards and one touchdown.
Known more for his blocking skills at two positions, Johnson gives the Steelers the tight end/fullback they're lacking with the departure of Will Johnson.
The Steelers have opened the season with at least four tight ends (five in 2013) every year since 2011, when they had only Heath Miller, Weslye Saunders and Will Johnson.
Roosevelt Nix is entering his second season as the starting fullback.
The team released rookie David Reeves to make room for Johnson on the 90-man roster.
