I like the move for Miller. Not a fan of him as an Rb1 for fantasy but the volume is there and he would be any upgrade over your current roster. I assume this is a redraft (or seasonal) league. I would push Snead for Miller straight up. Start there.
He should bite based on the Snead hype, but he's the one I would dish because Brees can spread the ball around to so many different receiving options not named Fleener.
