The 49ers went and got McCaffrey to complete their offense. McCaffrey had plenty of wear on him when the 49ers acquired him and had missed 23 of 49 games in the three seasons before the trade.
Let's imitate the 49ers one more time and get our last key piece, a difference maker at WR to complete the offense. He hasn't missed a game in three years, and led the league in receiving touchdowns the last time Carr was his quarterback.
