How fast are your safeties (spd, acc, agil)? and what are their zone / play recognition / awareness?
I only ask because usually when I run cover 2, I get torched by streaks to the side-lines, but it may just be because my safeties aren't good or fast enough.
My safeties are:
Troy Polamalu (97 ovr)
91 spd, 92 acc, 93 agil, 89 zone, 95 playrecog, 92 awr
Kerry Rhodes (88 ovr)
84 spd, 87 acc, 85 agil, 90 zone, 87 playrecog, 91 awr
I know Rhodes is a bit slow, but he's got great awareness/zone/playrecog.
Either way, even troy gets torches in the cover 2.
