The video Mav posted is a really good example of why this offense is so hard to stop. I like this video because it’s against good defensive play. They’re not poorly aligned, there isn’t a bust, just an example that you can’t cover against everything in this game.
The two safeties are split, with a LB shading between the trips set to the field side and the formation. Both safeties are about 10 yards deep, giving decent run support. The LB in the box can fill any gap because he has two contain players to the top and bottom. The problem is that trips set is so wide that there is going to be no help over the top and that’s what’s dictating that outside CB the most. A good route, as seen here, and he has practically no chance.
This pass concept is called a ‘snag’ or ‘triangle stretch’. It’s easy to see why if paused near the end of the video as you can clearly see the triangle shape. It’s a primary passing concept in this offense as it stretches a defense both horizontally and vertically. It’s good against man and zone. The out and flat receivers are a high-low read to the outside and that spot route just sits in a hole.
Frost juices it up with the threat of a QB run. Finally, that’s a ridiculously tough throw, running left then torquing the upper body back the other way. This is why Mario seeks out athletes that can throw on the run, not just anybody can make this throw. This play really highlights the lethality of this passing game married to Martinez’s ability.
