In hindsight, if Ime didn’t use that challenge on the JB charge, he could have done so to contest the alleged goaltending call? Just one of those things.
Well, challenging that call was a poor decision.
Eh, that's almost an automatic challenge if you have it there in that situation, because charge calls are always bang bang and the slightest movement can offset a charge call. And it was an All-Star versus a no-namer in White, which usually favors the star player. Don't forget he has to make that decision in a split second.
I think it was a reasonable challenge in that scenario. Besides, it's not like Ime would've been able to challenge the last potential goaltending call anyways. He wouldn't have been able to call a timeout there, which is a prerequisite for the challenge. (Also, he's as bad as Brad at not calling the timeouts on end of game broken possessions that clearly need a timeout (e.g. the forced Smart layup with shotclock running down); highly doubtful he would've called a timeout there even if he had time.)
