Willis is one of the league's best at making defensive adjustments.
A team is only as good as its leader, and outside of head coach Jim Harbaugh, no one leads the 49ers like Willis does.
Everyone knows that Willis is an incredible leader on the field. He's the one who makes all the on-field defensive adjustments, and he does it very well. There's a reason that the 49ers were ranked fourth in total defense last season.
But even off the gridiron, he acts as both a friend and a mentor.
Kevin Lynch of SFGate.com reported that Willis was recently asked by NaVorro Bowman to become the godfather of Bowman's twins.
In his typically humble fashion, Willis told Lynch:
That's probably one of the biggest things, as an individual, is to be asked to be someone's godfather. For him to ask me, I was like, 'Man, really?' I don't know the first thing about it. But I'm just a phone call away or a drive away, and I will do the very best I can.
The camaraderie that the 49ers have on and off the field lends itself tremendously to the team's long-term success, and Willis' leadership is its driving force.
