Allen's pedigree is defensive wizardry, but the Raiders might have the AFC's worst unit in 2013. Until more talent arrives, Allen will struggle to put his stamp on this group the way he did with the Denver Broncos' D in 2011. The win-loss record could be ugly, so it's important for Allen to win the public-perception battle, making his vision clear for everyone from owner Mark Davis down to the 8-year-old Raiders fan wondering when Sundays will be fun again.
