Standalone value: we so easily forget this standing in the comfortable months of August, but the bye week gauntlet portion of the fantasy season is brutal. Especially if you play in competitive and deeper leagues, finding fill-ins for your starters some weeks is difficult. It gets exponentially harder to find replacements when you have a non-usable backup running back clogging up a roster spot just in case the starter goes down. Bush was not completely worthless as a fantasy asset prior to McFadden's injury, because he was the team's goal line back. Three of Bush's seven 2011 rushing touchdowns came in the first six weeks of the season, and with McFadden in the lineup. This reality also played into his 9th round ADP. There was risk in playing him, but at least there was upside for more than a two or three point relief duty fantasy day. Remember this one; it should be the crucial verdict in deciding whether to choose a running back handcuff. If the backup you are considering is strictly depth, and will not be suable for your fantasy team without an injury occurring, it's better to just pass.
