How much of an impact is it on brady that the last two years the offense has been more tightens centered compared to this year where it is more wide receiver centered

Impact on Brady? Not much. The Patriots have run a lot of the same plays and just change up the personnel, so I think a lot of their offensive evolution outside of 2007 and 2013 is more directly tied to the strengths of their players. 

I never thought they purposely said “we need to go to a two tight end offense” in the 2010 draft. Good players were available, they drafted them, and adjusted their offense to fit the pieces they had.
