I've started figure out how to 1turn score with Norse (my usual tournament team) one year ago, and I've discovered that possibilities are multiples.
The 3-4-4 defence isn't so effective as Ian point out, as opponent players go to fill some square you need (even if you need some dodge if you don't field a mino and have not all of your blitzers available). Better the other option, with 8 man covering all the line 3 (being 1 the END ZONE).
In this case, it doesn't matter if the 3 on the line are adjacent or separate.
After lot and lot of study, (you know, I'm crazy on losing time on this, but which of us 30+ aged men still playing little "puppets"

is not?) I discover different ways to score.
I can do it even with 9 men if I field the mino, but now that I field the Ogre I need 10, and only 2 frenzy blitzer (only?!?

).
This is still higly higly difficult and against most of "statistical laws" (lot and lot of dices), but NOT impossible.
How to do it? I cannot reveal my secrets, othewise everyone gonna beat me and avoid my score

.
Plus it's more effective when your opponent doesn't expect your temptative. Ask Miloquaser (DO05, failed for a double smash on second block) or Blitzwing (PKQ2, failed only because... he INTERCEPT my pass to the catcher

)
BTW: oviously even dwarves CAN score in one turn... but there's more and more dices to roll

... still, DIFFICULT, NOT IMPOSSIBLE!
Watch out: There's Panico in the stadium...
