Isn't that also called a trap block?
Yes, it is. What makes it a "wham" is when it's coming from a player in the backfield, coming across the formation, rather than the OL.
This is a really good read that I believe describes a lot of what I'm seeing:
http://breakdownsports.blogspot.com/2015/05/inside-playbook-trap-and-wham-run-play-meyer-ohio-state-harbaugh-michigan-state-dantonio.htmlBeginning with the Influence Trap section, I think it describes pretty well what we're doing. It's zone blocking, but pulling OL in different directions to get the defenders to flow one way, and then taking them out with a trap or a wham - or just leaving backside guys unblocked and letting the backside OL do damage at the second level.
Jamaal's
62 yarder against MSU wasn't a wham, but it's a great example of influence blocking. We send the FB to the strong (left) side as an influence block. Most of the OL zone block down that direction, and leave the backside defenders unblocked. The RT, however, goes immediately to the second level to chip the WLB. The DTs, strong side DE, MLB, SLB, and SS all follow the blocking to the strong side, taking them all out of the play. Jamaal counters to the backside, and he hits it hard. The unblocked DE on that side whiffs, caught deciding between running down a potential sweep from behind and maintaining his gap so nothing breaks outside. The WLB, after being chipped, only has time to make a futile dive (I love the immediate celebration from the RT; he immediately knows he did his job and the play is going for a huge gain). The only guy with a shot at him is the FS, who eventually chases him down after 62 yards.
There's some of the same stuff in Jamaal's TDs against Toledo. TD #3 could have been the same play as the 62 yarder at MSU. TD #4 might also be that play, but the backside guys stay home, a seam opens play side, and you two OL completely free to the second level. TD #5 has a wham from Algie (or, would have if the DE didn't charge so far upfield) plus Kurtz blocking from the outside in. With a guy that hits a hole as fast and hard as Jamaal, one mistake or hesitation by anyone on the defense and these plays are going for big yards. They have to pick their poison, and Jamaal has the vision, speed, and power to hurt you whatever you choose.
The point is we've got a ton of variety and misdirection in our blocking schemes, and I love it. A bunch of the plays we're running in the article I linked, and given who else is running them and how much success they've had doing so, I'm very pleased.
