Alvin Kamara just had to acknowledge the milestone. His former teammate, Adrian Peterson, logged a career-high 37 carries for the Arizona Cardinals last Sunday. So Kamara, the New Orleans Saints' dynamic rookie back, reached out to Peterson. "I texted him and said, ‘Well, I know you’re in the damn cold tub. For real' " Kamara told USA TODAY Sports on Wednesday as the Saints prepared to take their six-game winning streak to Buffalo. Kamara, a third-round pick from Tennessee, played with Peterson for just four games before the Saints dealt the veteran to Arizona. But clearly the youngster is still connected to "AD," especially when considering his own increased workload since the trade. “I knew my role was going to change,” Kamara reflected. “Of course, the snap count was going to change. I knew I was going to have to do more. At the beginning of the season, I wasn’t doing too much pass protection. I knew that was going to change, and I’d get more touches.” The emergence of Kamara, who leads the NFL with an average of 6 yards per carry, is one reason why Peterson was expendable from a crowded New Orleans backfield that also includes Mark Ingram. Kamara's impact was on full display during Sunday’s thrashing of the Tampa Bay Buccaneers, when he had the first multi-touchdown game of his young career. Kamara rushed for 68 yards and a TD on 10 carries and caught six passes for 84 yards, with a scintillating 33-yard TD when he fell to the turf after hurdling a would-be tackle, then sprung to his feet and darted to the end zone.
