I see your point with regards to what numbers show but they have our number and this could easily be a tight game going to them.
The Patriots have the Giants number in the regular season. In the Kraft era the Patriots are 4-1 vs the Giants in the regular season. Ok, if we get to the SB and the Giants are there then it's time to panic, find a ledge, build a pillow fort and get in it, find the nearest college campus safe space. Otherwise history says the Giants will lose.
FYI, the lone regular season loss to the Giants in the Kraft era was Nov. 2011. It is where Brady had 2 ints (his total for the first 8 games of 2015) as well as the Patriots fumbling the ball away twice. The Giants scored a TD in the last minute against arguably(?) the worst D the Patriots ever fielded in the last 14 years. With all due respect to 2011 and the exciting season it was, the fact that we were in position to win the SB over the Giants if WW makes the most important catch of his lifetime is frigging astonishing.
That regular season game saw important D contributions from Kyle Love, Gary Guyton, Josh Barrett, Andre Carter, Phil Adams, James Ihedigbo, Tracy White (again, how the F did we get soooo close to win the SB??). All love for these guys who gave it their all, but comparing them to 2015 D is silly.
Our D now is
markedly better on the DL, at LB, even at secondary (our secondary was appalling in 2011), with pass rush a notable major difference. Gost is a better kicker and STs are overall better. 2015 Brady is a better QB (IMHO), Gronk is a better TE, JE is >= 2011 WW, LaFell much better than 2011 Branch, DA much better than anyone left at WR in 2011 (urgh-Chad Johnson). But to be fair to 2011 -- The Prisoner > Chandler though Dobson > than whatever else there was at WR). IMHO Blount is > than BJGE/Ridley (though it is arguable), but 2011 had Woodhead, where we have lost Lewis (too bad about Lewis as he was showing he was > than Woodhead but I liked Woodhead and wish we had him now).
Another important point: the Giants 2011 were 6-2 coming into the Patriots game. They are 5-4 now. Stats say the 2015 Giants < 2011 Giants.
So come on brother, "they have our number" is along the lines of 'I saw a black cat before the game' or 'I walked under a ladder' or 'spilled the salt'. It's silly given the last matchup was 4 years ago. The Patriots are clearly the better team and are likely to win, period. Sure, any given Sunday is always in effect but that doesn't change that the Giants are not on the Patriots level despite, ahem, games played 4 years ago and 8 years ago.
Bottom line: as long as we do/execute what we do routinely and the Giants do/execute what they do routinely, we will very likely win this game.
