I've been doing well in my sophomore season.

How do I beat this formation? I think it's illegal, but I've noticed that my opponent got 43% possession in his last game in a win against a team with a legal formation:

2-3-3-2

----DC--DC----
DML--DMC--DMR
---MC-MC-MC---
----ST--ST----

If he changes to a 3-2-3-2 at the last minute, what should I do...

---DC-DC-DC---
DML--------DMR
---MC-MC-MC---
----ST--ST----
