Thats the only way we would be able to successfully play defense...what happens if you play lets say the colts, its 4th and short, you put in goaline and blitz the house, expecting a run, but then they come out in 5 WR set and there is 5 open receivers? That wouldn't be realistic at all, I have always used this feature to call my defenses.
0 wr, 3 te's=goaline
1 or 2 wr=4-3 or goaline
4 or 5 wr=dime 3-2-6
Thats how I call mine. Then on Wildcat, I usually put in dime 3-2-6, and do a zone blitz. Man coverage will get raped with the wildcat.
