Three Team Blood Bowl

For those times when you have an odd number of coaches, I've always thought it would be great to have a three team version of Blood Bowl, so everybody could play. Recently, I've put a little more work into this idea.


The first issue that stands out to me would be the board. I've seen three different ideas for this:
1. Hexes. I'm leaning mostly towards this, I think.

2. Square distortion. I really like this idea, which works great for everything EXCEPT passing. I'm mocking up a board like this, though, to try it out.


3. Irregular player positions to make squares fit.
As laid out in Tri-Bowl.
I started a thread on this over at talkbloodbowl.com (you'll have to register to see the thread).
