I do agree that the Mustangs have a system that is in place that gives them a great advantage.
But I also agree with the point that they are playing with above average players. No, they don't "wow" you during warm-ups, but smart athletes that play other sports (basketball, baseball, track) do not exist at other schools with the frequency they do at Lipscomb.
They are not always very big in the line and do make up for that by scheme and technique, but their backs and linebacker are above average for the region and would start on all of the region opponents teams with a few exceptions.
