Sammy inherited the Buffalo Bills RB room from Sam Gash (1998–2003), and handed it to Larry Centers (2001–2002).
Sammy inherited the New England Patriots RB room from Laurence Maroney (2006–2009), and handed it to BenJarvus Green-Ellis (2008–2011).
Sammy inherited the Miami Dolphins RB room from Travis Minor (2001–2006), and handed it to Ronnie Brown (2005–2010).
The room is reconstructed from arrival order among durable members (≥4 seasons with the club) at the player’s position group — a lineage by arrival, not a week-by-week depth chart. Distinct from the league-wide positional GOAT torch.
