The Patriotsmade the announcement Sunday night and would only say that McDaniels is joining the team as an offensive assistant for the remainder of the season. However, a league source told NFL Network insider Jason La Canfora on Saturday that McDaniels will become New England's offensive coordinator once O'Brien leaves after the season.
McDaniels spent 2010 first-round draft picks on wide receiver Demaryius Thomas (22nd overall) and quarterback Tim Tebow (25th overall), whose 80-yard touchdown connection in overtime Sunday night gave the Broncosa 29-23 wild-card victory over the Pittsburgh Steelers.
Now, McDaniels will be reunited with Brady and another prolific offense. The Patriots were second in the league in overall yards with 428 per game and passing yards with 317.8 per game. Their average of 32.1 points ranked third.
