There will be big playoff implications for Oldham County and GRC when the two meet this coming Friday in Winchester. Oldham County (3-2, 1-1) is coming off a disappointing 25-20 loss to Bryan Station.   The Colonels'  5 games this year have been decided by 7 points or less four times; only Oldham's 13 point win over Madison Central two weeks ago had a multi-score margin one way or the other. George Rogers Clark (1-4, 1-1) got their first win of the season Friday with a resounding 48-15
