Yeah, there are all sorts of things that Belichick "would never do" until he goes and does them. Trading up for Jones, trading up for Hightower, and trading for Cooks were all out of Belichick's usual MO at the time they happened but he did them all anyway.
At this point, I don't put a lot of stock in that stuff. Nothing Belichick might do would surprise me all that much; I still believe there are strong general trends in how he handles the draft and player acquisition in general, but he's repeatedly proven he's willing to step outside of that and make big moves if the player in question warrants it.
