The San Francisco 49ers secondary is big, young, and hungry. We're joined by 49ers rookie defensive back Adrian Colbert, who explains to Al and Zain what he can contribute to the group. Colbert is also the cousin of 49ers receiver Marquise Goodwin, who he once said he would love to cover in man coverage. Find out who he said is the faster of the two and what he thinks of's "official" listed 40-times.

Also, the guys break down the back end of the defense and debate whether or not the inexperience could put it behind the eight ball.
