College football is all about cultural continuity. Coaches are hired to install foundations on which future teams are built. Older players develop collective identities that in turn become foundations for recruiting and developing younger players. Eventually, it becomes the bedrock for the entire program, and it becomes the easiest recognizable piece of discussion when opponents discuss and prepare for a game.
Steve Addazio loves to reinforce that point because the Boston College program is now entirely built in his desired image. His fingerprints are on the program's entire identity, an enhancement of what he believes a Boston College football team should look like.
