Bad tackling, defensive execution, and simply being physically outplayed in the trenches were all factors that led to Patriots’ 1st quarter woes against the Broncos in week 15. In fact, the bad tackling continued for both teams throughout much of the game, although the Patriots really cut down their struggles in this area after the first quarter which helped them significantly. Still, it looks like tackling, such a fundamental football concept, is going to be one of the major factors to watch in the Patriots-Broncos playoff rematch this Saturday.
