Africentric is an interesting team to watch play. I'm not sure I have ever heard anyone claim that they are amazing at execution. What they are amazing at is pressure and intensity, turning steals into layups, and offensive rebounds leading to points. So, they will not execute and look bad for a stretch, then they will make a steal and score a layup, and then get an offensive rebound and a score or two (or three), and you can't overcome it.
Coach McKinney is a very good coach. I will now say something controversial: he has accomplished a lot with a lot.
