Things heated up in Foxborough on Thursday as temperatures soared above 90 degrees but that did little to jumpstart what has become a sluggish offense. Whether it's uncertainty related to a new scheme, defensive dominance or simply a lack of execution, the offense remains a work in progress.
After a week-plus of watching the struggles, the answer seems to be more execution-related than anything else. For all of the talk about changes in schemes and the identity of the play caller, none of that would seem to of particular import in a practice setting. The plays are generally scripted with the players well aware of their assignments each day.
