Yep. Diamond. Baltimore ran what looked like the same play out of it last week. The Ravens have multiple wrinkles out of it including some QB run. It can be pretty wild at the snap with 4 guys all going to different gaps. Lots of eye candy for LBs and Safeties.Actually they lined up in the diamond formation. He was at the top . They handed off . But you are right just another formation for opposition to work on in practice and try to figure out how HH will be utilized and they have to commit a defender to account for him.
