Ridiculous that they can't review that stuff in the last two minutes they need to give a coach a challenge flag. DD
If I'm not mistaken, the Rockets (Les/Morey) have been against replays; feeling it slows the game down to much and isn't good for fans. I guess they wouldn't really like the challenge flag idea either.
Even if they did allow reviews, I doubt fouls would be a part of it. Just like how you cannot review things like Holding, Passing Interference, etc in the NFL.
Very good idea. Now that the review center is available, this practice is mature. If the NBA want, they can limit the use of the flag by adding a condition. For example, if one challenge is unsuccessful, they will be suspended from using the flag for one game.
