This is one of those topics that could go on endlessly and depending upon the criteria chosen(game or games you saw, single game, single season, career, high school, college and/or pro careers) Virginia produced lots of names and in the over 60 years that I have been blessed to watch high school football in Virginia. There are too many to mention them all.
Harry Dalton is in that discussion as are Henderson, Wilson, Davis and the others mentioned in this thread. Having mentioned those the names not mentioned, to name just a few, include Terry Kirby, Thomas Jones, Cyrus Lawrence, Dennis Mahan and on and on. There are also guys not mentioned that play in programs where even if you are a star the upper class guy was just as good and you wait your turn or playing in a smaller classification causes people to question the talent. Then there is the cruelest fate of all, a career derailed by injury, such as former Salem/VT back Marcus Parker. He still had a great career but, the what might have been is still there. Finally, for the really old timers still here and reading a shout out to the likes of Ed Clark and Famous Amos Lawrence and apologies to the many more omitted just due to lack of space.
