Latavius Murray isn’t worried about the Vikings run game struggles last season; he’s focused solely on the way he can help improve Minnesota’s offense in 2017. Murray, who spent the first four seasons of his NFL career with the Raiders before signing with the Vikings early Thursday morning, said he’s aware of the obstacles the Vikings offensive line faced in 2016. Over 16 games, Minnesota started eight different combinations of linemen, with 12 different players seeing action on the line throughout the year. “I just know that some unfortunate injuries happened last year,” Murray said during a conference call with Twin Cities media members Thursday. Murray has experience with Vikings offensive line coach Tony Sparano, who was in Oakland during Murray’s first two seasons. Sparano served as the Raiders assistant head coach and offensive line coach in 2013; after Oakland started the 2014 season 0-4, Sparano was promoted to interim head coach for the remainder of the season. “I’ve worked with Coach Sparano, and I trust in his process and getting the guys ready,” Murray said. “I haven’t met [the Vikings offensive linemen], but there are some guys there that they brought in and some guys that were already there and capable. “Any year that’s a new year, you have to go in and put the work in,” Murray continued. “We’ll all get a crack at this thing next year, and that’s all that matters, and not what happened last year. That goes for, I’m sure that line, and that goes for me and my play. That’s the only thing we can focus on, just moving forward.” A couple of hours prior to his conference call, Murray posted a photo on Instagram of himself and running back Adrian Peterson, whom Vikings General Manager Rick Spielman confirmed Thursday will not be re-signed by the Vikings for the 2017 season.
