This may be far fetched, but I am going to pose the question anyway.

Yes he is that shallow. The records and the money keep Drew Brees playing. That is who he is, besides being a great QB.
Its doesn't bother me at all. As long as he puts the Ws up for the New Orleans Saints God bless him. I am a New Orleans fans. I'm not a Saints fan, I'm not a, name any player, fan. I am a New Orleans fan. As long as a player is helping the New Orleans team win I like him. Also go back and read the "Brees is done with New Orleans after he retires" I don't hold it against him that he wants to move and live in SD after his playing days are over.
Everything you said has merit. But in this potential upcoming situation (season), there are a lot of other factors for him (other players), to weigh. What about staff, such as coaches, trainers...etc., that may be at higher risk, due to age and health issues? I would think most players would be asymptomatic. But a few NBA players weren’t and paid for it by getting sick. We shall see soon enough.

At the end of the day, before any game is played, or before any organized team practices are commenced, the NFLPA is going to have a lot to say about it all.
