If he is indeed planning to trade the #1 pick, you don't give that info now. Yes, you will have teams trying to bid on that #1. However, you also give them a lot of time to think on what they are willing to give up. If you make it public right before, it creates a frenzy and teams don't have time to think and decide against it. It's human nature that if you are presented with something that you want real bad, but you have to make the decision right now, more times than not, people give in to the knee jerk reaction and do it no matter the cost. It's when you have the time to step back and analyze it that your emotions come out of the equation and your rational and calculating mind takes over. Keep the emotions in it...along with a short time limit, and that is when people are willing to give up more in order to get what they want. A good example of this is what Kevin Costner did to Jacksonville in Draft Day.
I don't know if he is planning to trade it or not. Frankly, I don't give a crap. He's going to do what he wants to do and none of us know what that is nor can we control it. Just giving a possible reason why he may be playing it this why IF he decides to trade it away.
