Between those 2 I'd say Gibson this week.
But, I would say Givens above Gibson. Although Gibson is a solid 6 points in standard scoring, Givens gets almost the same amount of looks and is MUCH more explosive. Easily the second talented person on the offense behind Bradford. Givens could get you 3 points, but he could go for 20+.
