Too much garbage for Brady to sort through in 2006, 2013 & 2019.
Forget 2008. Season was over the moment Brady's knee got destroyed.
2009 was a tall ask with Brady coming off the ACL. The Welker injury was the nail in the coffin.
2010-2012 was a tremendous stretch for Brady. The NE defenses were trash, which arguably wasted the peak of Brady's ability.
In 2015 poor decisions by Belichick cost the team three games: PHI, @NYJ, @Mia. Subsequently they lost the #1 seed which resulted in them being totally overmatched @DEN in the AFCCG. The Broncos had a powerhouse offense that season but Peyton loses that AFCCG if it's in Foxboro.
2017: Malcolm Butler. No need to elaborate.
