The acquisition of Talib has tightened up the whole Patriot secondary. Not the same pourous D as the beginning of the season. Rookies have settled in and gained experience and confidence. Pats run D shut down Foster for 42 yds after making a quick adjustment early on.
Pats offense is second to none at this time. When Gronk returns Brady will have another weapon in his arsenal. The Pats running game is something that has to be accounted for now. It's not all Brady's arm.
Being the homer that I am, I like the Pat's chances at being in another Super Bowl, but like has been said many times, Any Given Day.
