Back to the OP: These people are sportsphiles-not likely to be linguisticly gifted, or know much about unfamiliar sports linguistics. Listen [if you dare] to their usual speech patterns--I find them absolutely awful. They are a reason why I dislike remote sports listening or viewing. Silence is something their industry cannot accept, and thus their verbosity knows no bounds. I wonder if any of them have more that yr 10 qualifications, because they sound so uneducated, & a better qualified person would surely choose a better job? What they are doing takes only a specialized memory, not real intelligence.
