No, I don't think I can.
I was in direct sales for seven years before returning to pharmacy and I'm also responsible for selling my photography biz. Friends, family, and clients have told me that I could sell deep freezers to eskimos -- certainly nice compliments. But I don't think that Dale Carnegie himself could sway Favre as much as the money and his family.
It's unfortunate that so much drama has surrounded Favre over that last few years. I hope that when he actually does hang up the cleat for good, that he will be remembered for his accomplishments on the field and not the drama.
