Never has a veteran locker room presence been so important.
Caron Butler only lasted one season in Detroit, but he's definitely one of "those guys" teams are happy to have around.
Being a veteran to show the young guys how to do things is often overblown, but in Butler's case it certainly applies, at least at his current rate of acceptable production.
The reason Butler's voice carries so much weight is not just because he's spent 13 years in the NBA and has a few All-Star appearances under his belt. It's because he lived a life.
