IRVING — How do the Dallas Cowboys beat double coverage on Dez Bryant?Jerry Jones says you throw it to him, anyway.“The same kind of throw you throw to him in the end zone the other day that he made that catch — he can make that catch with two people on him,” Jones said on his weekly radio show on KRLD 105.3 FM “The Fan” on Tuesday. “You throw him the ball when he’s double-covered. You can do that.”Bryant caught two touchdown passes against San Diego, one a leaping grab over cornerback Richard Marshall and another on a 34-yard catch and run in the middle of the field. He wasn’t doubled on those plays.Jones’ point is that Bryant, with 23 catches for 282 yards and four touchdowns, can be counted on for even more, given the chance.“Dez is going. He’s blowing and going,” Jones said. “He’s doing a great job. He’s a far better player than he was at this time last year. He’s going to get better. But that’s what we’ve got to have throughout the team.”Spencer surgeryAnthony Spencer had successful microfracture surgery on his left knee Tuesday, according to his agent, Jordan Woy.Woy said Spencer should be 100 percent by February or March. He said everybody recovers differently, but Spencer should recover faster than most.Spencer was placed on injured reserve last week and has been replaced in the starting lineup by George Selvie, who has three sacks this season.Spencer’s absence was exacerbated Sunday when Selvie suffered a head injury against the San Diego Chargers and is questionable for this week’s game against the Denver Broncos.Spencer is guaranteed $10.6 million this season as the Cowboys’ franchise player. He will be a free agent in March.Spencer missed all of training camp and the preseason after undergoing arthroscopic knee surgery July 25. He played briefly against the Kansas City Chiefs in the second game of the season before suffering a setback, resulting in the decision to try the complicated microfracture surgery that will also use stem cells to promote cartilage growth.Tiny holes were drilled into the bone. Blood and bone marrow are supposed to seal the fractures, creating a super-clot that turns into cartilage over time.The bench approachThe Cowboys have not been afraid to make lineup changes this season to put the best players on the field and demand accountability.It started in the preseason when Cowboys coach Jason Garrett benched running back DeMarco Murray for a half after a fumble. The first four games have seen three players replaced in the starting lineup — cornerback Morris Claiborne by Orlando Scandrick, safety Will Allen by J.J. Wilcox and guard Mackenzy Bernadeau by Brian Waters.On Sunday against the Chargers, linebacker Bruce Carter was benched in the second half after giving up two touchdown passes in pass coverage and losing confidence.“I think we’ve always strived to make everybody feel accountable for what they’re doing around here and oftentimes competition allows you to do that better as a football coach and as a football staff,” Garrett said.Romo meterTony Romo is the fourth-rated passer in the league, but that has only produced a 2-2 record.Romo has a 105.0 rating for the season, which ranks behind only Peyton Manning’s 138.0, Philip Rivers’ 118.8 and Aaron Rodgers’ 105.1.Manning is undefeated, while Rivers, Romo and Rodgers are a combined 5-6. The fifth-rated quarterback, Drew Brees of the Saints, is 4-0.
