This is a trend on Kansas City's defense. The Chiefs have traded for linebacker Mike Vrabel and signed linebacker Zach Thomas. Both of those players are in their 30s and are nearing the end of their careers. Yet, they are known leaders and could help an otherwise young defense.
Brown fits this mold. The former Chicago playmaker is 31 and has been hampered by injuries. Yet, Brown is a smart, instinctive player who can still help as an in-the-box safety. Still, the most value he can bring is as a leader.
The Chiefs have decent talent at safety with Jarrad Page, Bernard Pollard and young backup DaJuan Morgan. If Brown is signed, it would to help the lead the way, which is the same reason why Vrabel and Thomas were brought in.
