At least one a half? Kind of tired seeing a terrible call go unchallenged because the coach doesn't want to use it in the first half?
Yeah, it doesn't seem right to lose the availability of your challenge because you use it and successfully challenge a bad call.
Good move given how games have been called these days. Hell give them a challenge a quarter if they don't lose one.
Yeah agreed there should be no limit, until it's an unsuccessful challenge, then you don't get any more. I'd like to see them speed up the review process.
