HCA played a small part im sure, but the CT vs normal is what lost you the game, look at my game and you will see what i mean.
i had the lead the entire game, up until the 4th quarter where he outscored me 33-12
now, you can usually count on HCA giving the home team a strong 4th quarter but my HCA went out the window here.
I think, HCA and each GDP selection amount to about the same impact on the outcome of the game, i look at it like this, 70% team skill, (if its even that high) 20% Attitude 7% luck 1%gdp option 1 1% gdp option 2 1% HCA
maybe im wrong but thats sort of how i evaluate the games gdp and hca might account for a bit more, but i dont see them play much of a factor tbh, maybe 3-10 point swing either direction at most
