I don’t know if they considered him a bust but Miami, Dolphins and Chargers wanted him. That doesn’t seem like a “bust”.
The Chargers offered Brees a five-year, $50 million that would've only paid him $2 million the first season. In addition, the Miami Dolphins were interested in signing Brees, but ultimately failed to offer the quarterback a contract because they were scared off by his shoulder, which he had surgery on in early 2006.
In regards to Young….you are right he was considered a “bust” but not to the same extent as Lance. His physical skills were never in question. People are question if Lance can even be a backup.
