PS: People might not take that much notice of match commentators anyway:
Many years ago, a mate of mine got called upon at very short notice to provide reports on a Doncaster Rovers home game for listeners to BBC Radio Sheffield. He didn't know the name of a single Doncaster player, yet alone of their opponents, but he was handed a match programme as he settled into his commentary seat, meaning that he'd be able to identify each player from the number on his shirt.
The studio handed over to him periodically throughout the first half and he provided what he thought were accurate updates on the state of play. It was only at half-time though that he realised the programme he'd been given was a fortnight old. Not only was the Doncaster team significantly different by then but he'd been getting their opponents wrong (and, obviously, not a single one of their player's name right) for 45 minutes. Not one listener had phoned into Radio Sheffield to complain!
