Doubtful. These teams all have "spies" in other teams infrastructure so they have an idea whats going on. Thats why I scoff at theories like "the packers wasted the trade up cuz Van Ness would have been there at 14". Bellicheck wanted Van Ness and Gutes knew it. We, as fans, have a lot of theories that simply are grounded in our own fantasy of what we would be doing in their positions.
I don't hold Grudges. It's counterproductive.
