He was passed on due to character issues, so if some other team felt they were sorted out and his talent was worth a flier pay for a year of IR, they could have picked him up. Clearly none did, but the question remains as to why he was exposed to wavers at this time.
True, there was another Packer in 2010 who wouldn't settle and then complained that the Packers didn't bother giving him a ring after hanging about on IR the whole year. Never heard from him again after that.
