As much as we have, there's only context to really go on. Kind of a 2+2 type of thing. Ingram trade is announced, and not long after you got Cooks tweet. If nothing else, its awfully coincidental that Cooks seemed to be angry about something right as the news broke. Is that what happened? We'll probably never know, but that's all we have to go on right now.
I would lean more to it being about all of the trades Houston has done in the last couple of weeks, not just the MI trade to the Saints. I am sure Cooks feels like he is in no mans land now because of all the talent being dealt out.
