The block on Pennington was a block in the back. At the very least, there should have been a penalty from the 5, setting up the Ravens first and 10 at about the 15.
Gee, but Hochuli missed that, too.
....and that reminds me: many, many times in the game, Flacco had all day to sit back there, read the play, read the entire Sunday Times, and still get a pass away. And yet not once was there a holding call on the Ravens. Really? They held there blocks for 5-6 seconds, and not one of them did anything illegal? And yet on several of them they called illegal contact downfield on Miami. Some of them were questionable, but if that happened, why wasn't there ever holding?
