Brandon Lloyd had some mental issues, but he was still vastly underappreciated here by most -- and maybe even the team. He was signed to a 3 year / 12 m contract (if I remember), and many posters were disappointed by his first year performance and the reporting was that he was asked to take a paycut cause the patriots didn't believe his performance (and mental issues) were worth 4m/year; so he decided not to take it, and then probably didn't get any better offers cause every other team thought "if the pats don't want him, then there's something wrong" so he sat out a year.
It was obvious to me at the time that Lloyd was most definitely worth 4m/year; and in hindsight he'd have been a bargain.
