Very little was on TV back then. Most of the video of him is just the local news station clips they took to show on the evening news. However, the loss to Syracuse in 1977 is on YouTube. Might be some others there is well. If you can find the 1977 win at home against Kentucky, that's the game you want to see.
Both are good to watch, however Syracuse game is missing last minute or so and all the overtime. The Ky game is not a complete game but a rebroadcast with John Ward. Still very good. Also you may find the UCLA game somewhere.
