Brad Seely has left the Browns, a team spokesman said today. Seely served as the Browns' assistant head coach and special teams coordinator during the past two seasons.
Seely will now serve as the San Francisco 49ers' special teams coach, 49ers coach Jim Harbaugh told San Francisco reporters today. The 49ers will be the sixth NFL team since 1989 for which Seely, 54, has been a special teams coach.
This past season, the Browns' kickoff-coverage unit allowed an NFL-low 17.8 yards per return. Their punt-coverage unit ranked fifth, allowing an average return of 7.1 yards. In 2009, the Browns' special teams ranked in the top 10 in eight categories. They finished first in kickoff coverage (19.9 yards per return) and average drive start after kickoffs (31.4).
Seely is the third coordinator to leave the Browns since coach Eric Mangini was fired Jan. 3 and later replaced with Pat Shurmur. Defensive coordinator Rob Ryan was hired by the Dallas Cowboys, and offensive coordinator Brian Daboll joined the Miami Dolphins.
