Before the 2014-15 season began, I provided a list of the biggest matchup nightmares in college basketball. The players mentioned all featured different skill sets, but had one major attribute in common: They kept opposing coaches up at night. Often, it’s not creating a game plan to stop their ability, but rather limit it.

Now that we’re at the midpoint of the college season, let’s take an updated look at the top 10 list, with some familiar names from before and some new:

1. Jahlil Okafor, Duke Blue Devils

2014-15 stats: 18.9 points, 8.9 rebounds, 68.1 field goal percentage, 3.7 offensive rebounds

Okafor is the most complete low-post player in recent years. At 6-foot-10 with a 7-4 reach and huge hands, he is impossible to construct a game plan against.
