Tom Brady is "uncomfortable" with some of the Patriots personnel changes and what he perceives as a diminishing role providing input to gameplans, according to a report from ESPN's Chris Mortensen.

The report describes the relationship on both sides as "tense," with sources telling Mortensen that "nobody is untouchable" and a move to rookie quarterback Jimmy Garoppolo could happen "sooner than later." Supplementing that ambiguous timetable was a clarification stating that no source would confirm "sooner" meant a change to Garoppolo was coming this season.

Brady's frustration reportedly lies with personnel and coaching changes, specifically on the offensive line. Dante Scarnecchia, who had been with the team in a variety of roles since 1991, had served as offensive line coach since 2000 but retired at the end of last year. The new offensive line coach is Dave DeGuglielmo and because his group is so inexperienced, Brady's input into gameplans and pre-snap calls has been reduced. A source indicated that patience and a conservative approach are what's needed for the offense at this point.

"Sources say Brady is uncomfortable with the personnel and coaching changes, the consequences have led to tensions between Brady and the coaching staff, with Brady's input into gameplans, personnel packages, formations, pre-snap adjustments being significantly diminished."

The Patriots are 2-2 and coming off a blowout loss to the Chiefs in which Brady, the offensive line, and the skill position weapons looked overwhelmed. New England hosts Cincinnati Sunday night.
