He did. Brees and his wife invested in diamonds though and sued over the value of those diamonds. The more you read about NFL players and financial investments they make the more you wonder who the hell advises these guys...
I won't mention a name, but there was guy hanging around my little city in Canada that apparently had ripped off a number of NBA, NFL guys. My nephew was getting some Div 1 buzz in hoops, and turned down some low level DIv 1 teams to stay in Canada. During the recruiting process this guy showed up with Arizona state gear, pics of himself with a number of NFL guys, wanting to buy my nephew a coke etc. He said he was from ASU, etc. In the process of checking him out my sister spoke to ASU who said the guy had taken cash off lots of Suns, Cardinals, etc.
I mean he was clearly a fake, amateurish attempts at saying who he was, etc. But, guys had given him cheques, cash to set up summer camps etc. Later there was a semipro team and he was back in town, working in the office, where he took off with money. He never changed his name. My sister phoned the first person he said he worked with and they said he was a con-man. From time to time I have seen he is hanging around different teams, and people are still giving him money. He had even given people my nephew's name as a reference since my nephew as a reference. The mystery is how some of these guys keep their money as long as they do.
