One of biggest complaints about McDermott so far, is the lack of killer instinct. Is it play calling by Daboll? Is it execution? Who knows, but the foot seems to frequently come off the gas. Last year they had the chance against the Vikings, only to score 0 second half points. I seem to remember the play calling going ultra conservative in the second half. Perhaps they learned from that, because they dropped 41 on the Jets and 40-ish on the Dolphins to close out the year. And, again, it could be Daboll or execution as well. But something that concerns me and my very little football knowledge.
