That is a very good piece, thanks for posting.
I think it highlights something that most fans don't know and don't consider... making a trade is not about just calling a team and working out the details. The Chiefs sold the agent that KC was the best place for Mahomes, they got inside information during the offseason about him, they knew with as much certainty as they could get where they needed to get to to draft him and that it took someone that Reid has a long history with to be able to pull off the trade.
If the agent had told them that no one was showing any interest in him they would have stayed at 27 and drafted Mahomes.
I never said we would have to give up less picks if we added a player to the mix. Maybe the extra player would win us the trade. I would suspect we would still have to give up the same amount of draft capitol. The player would just be a sweetener to help get the trade done.
