I hear you, but that impact is rather minor. While it's tried more, it rarely changes the outcome. As someone else mentioned, taking a yellow to prevent a goal happens less frequently but when it does occur the advantage is often more substantial.
I'm less concerned with the intentional though, than I am the impact a ref's decision has on the games.
The risk of fouling out increases the variability based on how the game is ref'd. There are too many games (particularly college) where a post star seems to get the calls. Guys like Okafor are already better than the opponents. It seems to be too easy for them to get the other teams in foul trouble so that they end up going against bench players and now timid starters for most of the game.
