For the first time in a while, Cal has a HC with a defensive background. But what do we know about Justin Wilcox' defense? Words like “versatile” come up a lot, but what does that mean? In this post, I'll take a deeper look at the X’s and O’s of a Wilcox defense, and show you what background he’ll bring to his collaboration with DeRuyter and the rest of the staff. We'll see how his defense has roots in Bob Gregory's 4-3 (which was really a 4-2/4-4 in disguise), and how he shifted to a base 3-4 over time.
