In his first two years as an outside linebacker, Rey Maualuga was talented but undisciplined. During training camp defensive coordinator Mike Zimmer challenged Maualuga to become more focused and moved him inside, where he had played at USC. Maualuga responded with a career-high 88 tackles in 13 games for the NFL's seventh-ranked D. (He had 75 in 16 last season.) The 6'2", 260-pound Maualuga, who last year pleaded guilty to a 2010 DUI charge, credits part of his improvement to becoming a father last month. "I have something to wake up to, to play for," he said. "I know I can't be that Rey I used to be, that knucklehead."
