Stemming D Linemen? Pros and Cons

We did not stem a lot last year but we do stem. When we stemmed in our Multiple 40 I told the DL to get in the same gap just a different shade. For example, if I wanted a DE to end up in a 5 tech, he could eighter be in a 4I to start with or a 7 tech.

We would call our Defense like this: TO 31 Cover 3, Our defense would line up in whatever and when the MLBs made a MOVE call we stemmed. I liked it alot versus veer and wing T teams. If someone quick snapped us we told our DL to stunt to the stop the are suppose to be in.

Thanks

Here is how we teach our kids to stem. We use the standard three point stance. We start teaching early, for comfort, both right and left handed stances. What we tell the kids is that after the defense is called in the huddle, to line up one technique from what they are supposed to be in. For instance if the defense calls for the D lineman to be a 1, he starts out in a 2. If its a 2, he can start out either 1 or 3. We don't use a move call, they do it on their own. They can stem from one technique to the other simply by switching from a right handed to a left handed stance or vice versa. All they do is move the foot that is back, up and over and then put the other hand on the ground. We actually practice this in the off season with our running program. In addition to it confusing O line blocking rules, it looks kinda cool when they do it right.
