Amid TD streak, Packers running back focused on improvementWes HodkiewiczGREEN BAYJosh Jacobswalked into the Packers' offensive meetings on Thursday morning oblivious of his proximity to possibly achieving NFL history this weekend. In fact, no running back has even realized a 12-game streak with a rushing TD since San Diego Chargers great LaDainian Tomlinson in 2004. Jacobs rushed for 15 touchdowns during his Pro Bowl campaign, the third most by a running back in a single season in team history. It was Jacobs' 15th touchdown run during his 11-game streak and his 12th TD from inside the 4-yard line. Jacobs has generated 223 total yards in two previous victories over the Browns but left without a rushing TD, one of only eight teams Jacobs has faced multiple times but not scored against.
