Whatever kaleidoscope of butterflies toyed with running back Aaron Jones in the buildup to his first career start surely dissipated on the second play from scrimmage for the Green Bay Packers. Jones took the hand-off from quarterback Aaron Rodgers, turned the corner off the left side of the offensive line and followed a wall of blockers for an easy 13-yard gain. Two snaps later, Jones turned the corner again and was untouched for the first 4 yards beyond the line of scrimmage. He broke an arm tackle, rumbled across the line to gain and gobbled up another 8 yards to ignite a breakthrough performance that proved to the rookie he could succeed in the National Football League. “It shows that I belong at this level,” Jones said of his 19-carry, 125-yard performance while filling in for starter Ty Montgomery. And when the Packers returned to the practice field Wednesday to begin preparations for the Minnesota Vikings, the rookie was reminded that he couldn’t have done it alone. Said Jones: “Today when we were in the huddle Aaron (Rodgers) was like, ‘You got something to say to the O-line?’ I told them thank you, and Marty (Bennett) was like, ‘Hey, don’t forget about me and the receivers!’” Bennett’s point was well-taken after a game in which he and fellow tight end Lance Kendricks, along with nearly all of the wide receivers, provided excellent blocks to supplement a road-grading effort by the offensive line. Kendricks in particular had arguably his best blocking performance of the season and sprung a number of lengthy runs by winning one-on-one matchups against larger players.
