Two years ago, the circumstances were a lot different for Nnamdi Asomugha as he transitioned to a new team. Shortly after the lockout of 2011 lifted, Asomugha signed a big-money contract with the Philadelphia Eagles after eight seasons with the Raiders. He immediately reported to training camp on the East Coast to begin his crash course in a new defensive system. Asomugha lasted just two disappointing seasons in Philadelphia. This time, his contract and his familiarity with his new surroundings are completely different. "Making an adjustment with a full offseason and coming back to a place where I played before, in an area I know, the adjustment hasn't been hard," Asomugha said. Asomugha appears to be embracing the change after signing a one-year, $1.35 million contract. In Philadelphia, it was widely reported he often ate his lunch alone in the parking lot. In his short time with the 49ers, he has eagerly provided assistance to his young teammates on either side of the ball. "The locker room is great," Asomugha said. "It's really a good group of guys. And they told me that before I got here that was the case, but you never know what you're going to walk into. And these have been some great teammates, some hard-working guys. So it's been really good." Returning starter Tarell Brown does not take part in the voluntary workouts, choosing instead to follow his own speed-based workout regimen in Texas. Asomugha has lined up with the first-team defense during the 49ers' offseason program.
