Thanks for posting.... there used to be all those 1970 games posted on YouTube, but evidently someone objected & they disappeared for a while.
That SoCar game was the 2nd hottest game I ever played in - the hottest was the next week vs FSU. Both were 3:30 or 3:45 TV starts - I know, not so special today but ANY TV exposure was big then - with field temps, even on the natural grass at Grant Field, about 104 or so both weekends.
The heat played a big part in the SoCar game as their two big DTs wilted.
As for Harkey, that little flat pass he caught 14 times was a new wrinkle 50 years ago & went a long way to getting him drafted by the Jets
