Exactly, apart from the aspect of sport, rebuilding isn't an easy journey, most times it's comes easily and most times it's take the life out of you.
In sport, every fan looks forward for a rebuilding most especially when the team isn't performing close or it's expectations. Most times not even the players needs to be subtitued for a greater rebuilding to occur, the coach could be or the staffs. Like in the case of arsenal now, if you notice the team lacked team work and team spirit during the time of Arsene winger which I wouldn't say it was he fault but now that he has left, a new coach has came, with few new players, you can now see how arsenal are playing now, even if not to expectations but far fat better than before and like we now rebuilding doesn't just occur once as its a process.
Great article @broncofan99, You've impacted more life to me about rebuilding.
