A lot of teams are making changes to their coaching staff, but the Baltimore Ravens will stick with Jim Caldwell as their offensive coordinator.
Head coach John Harbaugh announced Monday that Caldwell, who replaced fired Cam Cameron during the season, will have the interim tag removed and keep the job in 2013.
Harbaugh said he expects to keep his staff intact for next season but did announce the addition of former Philadelphia Eagles defensive coordinator Juan Castillo.
The Ravens' offense has improved dramatically since Caldwell, the former Indianapolis Colts head coach, took over in week 15. Baltimore has averaged 417 yards per game since Caldwell took the reins and scored 21 points in the second half Sunday to rally past New England and advance to the Super Bowl.
Caldwell had never called plays in his 11-year NFL coaching career until Harbaugh promoted him.
Castillo was fired by the Eagles on Oct. 16. He'll work as consultant for the remainder of this season and then become the Ravens' running game coordinator next year.
---The AFC and NFC Championship games Sunday ranked as television's most-watched programs since Super Bowl XLVI, according to The Nielsen Company's Fast National ratings.
The Baltimore Ravens-New England Patriots AFC Championship Game on CBS drew 47.7 million viewers while the NFC title game between the San Francisco 49ers and Atlanta Falcons on Fox drew 42.0 million viewers.
It is the fourth straight year the two championship games each drew at least 41 million viewers.
---New York Jets owner Woody Johnson apparently was never fully on board with acquiring quarterback Tim Tebow.
Former Denver Broncos executive Ted Sundquist, who interviewed for the Jets' general manager job, told ESPN New York on Monday that Johnson said Tebow was "forced" on him and team president Neil Glat.
Presumably, former general manager Mike Tannenbaum convinced Johnson to approve trading for Tebow. Tannenbaum was fired after the regular season in which the Jets finished 6-10. The Jets hired John Idzik as his replacement last week.
---San Francisco kicker David Akers will keep his job for the Super Bowl despite missing another field goal attempt in the NFC championship game on Sunday.
"The decision's been made," 49ers coach Jim Harbaugh said.
Akers missed a 38-yard try that bounced off the left upright in the third quarter against Atlanta that would have tied the score at 24. The 49ers still won 28-24.
Akers has missed 14 of his last 38 field goal attempts, but he did kick a 36-yarder in the NFC divisional playoff win over Green Bay the previous week.
