More on Corwin Brown hire

As first reported by ESPN NFL Insider Adam Schefter, the Patriots have hired Corwin Brown to be part of their coaching staff. The Patriots are confirming that Brown has been hired, and here are a few quick-hit thoughts on the move:

1. Brown's official responsibilities are not yet defined. While he is likely to be working with the defensive backs in some capacity, there are still some moving parts as Bill Belichick fills out his defensive staff.

2. Josh Boyer was the team's defensive backs coach in 2009. It was his first season in that role after working as a coaching assistant. He could be affected by this move, although it is unclear how. One possibility is that the role of secondary coach could be split into two -- with a cornerbacks coach and a safeties coach.

3. Adding a coach with expertise in the secondary was something that Belichick probably felt was important based on the departure of defensive coordinator Dean Pees. When the Patriots broke down for positional meetings, Pees was often with the defensive backs.

4. However the coaching responsibilities break down with the defensive backs, one of Brown's biggest challenges figures to be with 2007 first-round draft choice Brandon Meriweather. Brown, a former safety himself in Belichick's defensive system, could play a key role in his development. Meriweather has shown flashes of excellence but also inconsistency at safety.
