He went from not having any issues speaking to having fairly significant issues almost overnight. No one's being hard on him, people are just curious. To me, he seems like someone's who's suffered a mild stroke and it's not merely a product of being 66 (which isn't terribly old), but that's just complete speculation.Sometimes I think these game threads are a little hard on Jack. He's 66 years old? Fast paced word retrieval is hardly atypical at that age and it is not like he is broadcasting golf. By a massive margin, hockey is the most challenging sport for play by play. And Jack compounds issues with the fatal flaw of clearly being a Bruins fan. He gets, apparently, too excited to speak correctly. It happens.
