By two weapons I'm going to assume you mean the following;
Code:
QB Brady
RB Green-Ellis Woodhead
WR Welker Branch
TE Gronkowski
That small list is me being kind and referencing who the "reliable" players on offense are. Brady has gone on record stating he'll be looking to spread the ball around more after his unusually high targeting of Welkonski last week.
So the answer is yes, the Patriots will score points. It's over to the Raiders to score more. We can argue about the Patriots turning into the Colts of old (which I loathe given my inclination toward great defense) but this is the new-age, over-officiated and high scoring Goodell NFL.
