responsibilities is to make sure that nobody gets behind him to make a big play. He lines up about 15 yards behind the line of scrimmage and get this, there are TWO of them! They often play cover two so each safety covers deep on their side of the field. Throwing it early will not help in a lot of cases because of the safety help over the top. The best way to beat this is to look the safety off and then hit the guy before the safety can help.
I hope we see a lot of man coverage because I think we finally have more than 1 receiver that can beat a CB or Safety 1-on-1
