He's not the first to charge out when he shouldn't, this team has a history of doing this in pressure plays toward the end of the game to defend field goals, only to have their pants pulled down by smarter opposition going wide and scoring.
Rate both Sue and Akoula over Spence, he seemed to be struggling. I would start with Sue and bring Spence on as a impact player for 20 odd mins. Alot of talent all waiting for their opportunity.
