The Pats don't like drafting two 1st rounders, period, due to the money they'd have to pay out. That carries way back to the days of Steinberg, when their scouting was among the best in the NFL at producing sleeper picks. This is one of those stupid holdover unspoken rules that for the Pats: "Don't draft two guys in the first round."
IMHO they will almost certainly trade away their picks, and quite possibly for a worse 1st round position than anyone is contemplating. They may turn some heads by drafting for the other team and doing the trade after the draft, completely confusing the analysts.
