It just does not make sense

I understand it when a 5-11 player shoots better from the arc than he does overall. When he gets in amongst the trees he is out of his element, and can get shots blocked regularly. But Drexel's Tavon Allen is not a shorty. He is 6-7. Yet he shoots 37.6% from the arc, but only 33.3% inside the arc. Doesn't make sense to me.
