Patriots coach Bill Belichick does not plan to name a defensive coordinator in 2010 and instead will be more involved on defense to share the workload with his assistants, according to the team's official website.
Also, the Patriots have not named an offensive coordinator at this point. If they do in the future, it would almost certainly be quarterbacks coach Bill O'Brien, who handled much of the play-calling duties in 2009 when the team went without an official coordinator. Belichick's comments today clearly positioned O'Brien as the leader of the offensive staff.
Pretty ballsy move imo. It's ALL on his shoulders now, I look forward to seeing how he handles the added pressure.
