I know nothing on a NT level but you seem to have brought up these sf/sg skills and motion.
My thought is . They had the right balanced team to play motion pin point excellent from my seeing, also you used Gdp. Please understand there is a penalty if you get it wrong and it huge one when we add the margin of error in your own team playing the tactic with the skills.. The more balance team will win.
I assume that your penalty in balance and getting gdp wrong ate up any edge in more effort. It became a skillful game of tactical input, Their sg/sf ate you alive because motion does equal coming off screen to shoot the ball and if the skill is correct the sf /sg will create his own shot as well it will be murder show.
I do see your defense working but they chipped away with the mis-matches created off the screens.. Some looked like they set higher screens to create baskets and some looked they were just wide open. I dont think it should have been 23 points route. But I do think you still would have lost given the margin of error you made wth gdp and how their player are more balanced skillful for motion. I think they really exploited your defensive edge with the passing.. Its was a beautiful game to watch.
I think you shouldn't have played Gdp. I think should have taken the gamble of straight up playing them. But take this with a grain of salt. Nt games are whole new world in which I know nothing about. Better luck next time. I guess.
