Browns look to fix defense plagued by missed tackles

Kruger and his defensive teammates had to sit through the videotape breakdown of their loss to the Oakland Raiders last week, when one Cleveland defender after another missed tackles.

Touted as one of the team’s strengths, the Browns are allowing an NFL-worst 158.3 yards rushing per game and Oakland had a 300-yard passer, 100-yard runner and a 100-yard receiver while rolling up 469 total yards in its 27-20 victory.

Browns coach Mike Pettine counted 14 missed tackles last week, but the issues go much deeper than not wrapping up ball carriers.

As the team prepared for this week’s game at San Diego, defensive coordinator Jim O’Neil said inconsistency has been the unit’s biggest issue.

The Browns hired Paul Dunn as an assistant offensive line coach to succeed Andy Moeller, who parted ways with the team following a domestic-violence complaint.

The winless Chicago Bears hope to get quarterback Jay Cutler back for Sunday’s game against the Raiders, but are preparing to go with Jimmy Clausen again if he is not ready.

Cutler practiced Thursday on a limited basis for the second straight day after sitting out last week’s 26-0 loss at Seattle because of a pulled hamstring.

Buffalo Bills coach Rex Ryan ruled out running back LeSean McCoy (hamstring) and receiver Sammy Watkins (calf) from playing against the New York Giants on Sunday.
