Merriman was a statistical force when healthy and those numbers will be hard to replace. Merriman first moved into the starting lineup during Week 6 of the 2005 season. Since that time, he's recorded 38.5 sacks in only 37 games, the only player to average more than a sack per game during that span.
Replacing Merriman in the starting lineup is Jyles Tucker, a promising second-year player who is long on talent and short on experience. Tucker began last season on the practice squad before being called up for the final six games. He earned national attention in the season finale when he earned Defensive Player of the Week honors against the Oakland Raiders, tallying three sacks, a forced fumble and a touchdown.
OLB Shawne Merriman
"I have to make plays within the defense and on special teams," said Tucker in an interview with SDBoltReport.com shortly after joining the Chargers. "I have to do everything they'll let me do. I have to work harder than the man next to me."
Rounding out the new three-man rotation at outside linebacker is Marques Harris, the top backup last season prior to Tucker's emergence. Harris posted 53 tackles and 5.5 sacks during his first three seasons. He has the potential to match those numbers this year given the abundance of playing time he can now expect.
Harris will be an unrestricted free agent after the season and is playing for his next contract. His former coach at Southern Utah State, Wes Meier, believes Harris has what it takes to cash in.
"He's got some of the best athleticism I've ever seen," Meier told SDBoltReport.com after Harris signed in San Diego. "He's got great strength and great speed."
Tucker and Harris do not have the dominant of ability of the man they will be asked to replace. However, they are certainly skilled enough help the Chargers' defense rank in the NFL's top 10 in terms of sacks.
