Minnesota Vikings star running back Adrian Peterson is no longer disgruntled. He's back in the fold, rejoining his teammates for an organized team activity Tuesday. "It definitely feels good to be back in the building," Peterson said. "Ultimately what it came down to was get back in the building. I've been working out hard, keeping my body in shape and it came down just to getting back in the building, being around my teammates, being around my coaches, getting back into the swing of things. I reached out, kinda gave them the heads up and said I'll be in town, I'll be coming in." "I've learned a lot from a mistake and I'm moving forward and I'm focused on what's in front of me and bettering myself as a person and professionally as a player," Peterson said, adding that he now uses timeouts instead of corporal punishment. Peterson previously said that the team hadn't been supportive enough of him during his child abuse case. "It felt good just to kinda be back, to be around the fellas, to be around the people that have been supporting," Peterson said. "And each and every guy has been supportive and the people in the front office. ... I've been knowing these people for eight years." Vikings coach Mike Zimmer was critical in Peterson's return. "We welcome him with open arms unequivocally," Zimmer said. "I love this kid, I really do. I wouldn't fly down to Houston to see him if he wasn't important to me." Did the team attempt to trade Peterson who has a $12.75 million base salary this year? "None," Zimmer said when asked if there were trade talks. "We've got an exciting team, an excellent young quarterback," Peterson said. "We can accomplish great things." Follow me on Twitter: @RavensInsider Aaron Wilson covers the Ravens for The Baltimore Sun
