Brett Favre is on drugs...
There I said it.
Its the only way to describe his behavior and decision making progress.
I guess it could be explained by other menatal illnesses. He could have brain damage. Either way, this guys needs help.
His drugs are attention and money. There are a ton of pro athletes who would do the exact same thing as Favre has been doing, if they had the chance, but luckily for all of us, there have been very few of these guys whose skills have still been salvagable at such an advanced age. Most of them have been forced to walk away before they can put themselves (and the rest of us) through this stuff.
It's not the fact that he wants to come back every year, it's the indecisiveness and lack of consideration for anyone else involved in these decisions.
These are behavior traits of a sick person in my opinion.
He's a narcissistic lunatic.
Eh, why should he be considering "other people involved", when they are letting him do this?
These teams could all give him a deadline and then walk away. However, they won't, so there is really no reason for him not to hold out on making a decision as long as he can.
Obviously, it is not the healthiest attitude in the world, but I really don't think it is that far from the norm. The difference is, most people have consequences for doing something like that, while he is given a free pass.
