Around the same height as you, I looked through my scouts and there was only 3 players with a height less than 180, they were 178,177 and 170. But since you can't see the players on the pitch on the game, I suppose it doesn't matter... You gave me a little thought, where are the 16/17 year old players in the game? I would do a probability modifier of getting more chance of 16/17 year olds as you upgrade youth facilities.
