The 1980 Olympics hockey game between USA and USSR was something special as well.

It would be really cool to get the endings of each of these games on one DVD.
Tennis:
I saw some tough matches with Jimmy Connors but I can't recollect any specific match and haven't paid much attention to tennis for many years though I am aware of big name players. There are just so many more matches going on throughout the year though Wimbledon may be the most famous of them all yet there are still so many others that would make it tough to narrow down just a few great matches. This one site states some of them for Wimbledon:

It would be nice to get a glimpse at some of these.
