Check off one more offseason project. Brian wrote a FAQ in 2009 but we've seen a lot of things since then, and I might do things a little differently, meaning it was due for a massive update. If it's a wonky word used in more than one Upon Further Review, you should be able to search it on this page. Sometimes opponents will have weird strategies or formations that I'll call out in that UFR. General Football Terminology What's the difference between strongside, weakside, playside, and backside? Strongside and weakside are pretty self-explanatory: if there's a tight end (or two) in the game or an offset H-back/fullback, the side with more players on it is the strongside and the other side is the weakside. Here, the strongside is to the top of the screen as that's where Kevin Koger is aligned. Some formations don't have a strong or weak side. Playside is basically the direction the play is run in, and is important on stretch plays mostly. If the offense is running to the right, the right is the playside and the left is the backside. These terms usually get mentioned in the following ways: The "backside" defensive end is the player who doesn't get blocked by the defense and is instead read by the quarterback. I'll often refer to a good block by an interior lineman, usually the center, as sealing a guy "lined up playside of him". What this means is that the defender lined up outside of the OL—closer to the area where the running back will attempt to cut the ball up—and still sealed him away. Other blocks will be described as an OL "getting playside" or failing to do the same, which basically means the OL gets between the DL and his attempt to flow down the line of scrimmage and tackle as the back cuts up.
