Putting one in for Dan "Spoonman" Spooner of the Indiana Pacers -
http://pbsl.ijbl.net/players/player270.htm
Dude put up close to 30 points and 11 boards with 3 stocks per game on top of that. His efficiency numbers and estimated wins added were about even with Sion's who did win MVP according to the computer. I'd nominate Sion myself, but I don't know what the rules are regarding self-nominations and getting the nomination point.
Anyway, Spooner's only 24, and notching all-league 1st team C while he still has room to grow shows you how scary of a player Spooner can turn out to be. When I came into the league, the Pacers were good for a long time with a team built around PG Deron Williams. Then they were good for a long time in the point-forward Herb Jones era. The Spooner era is next, and hopefully Pauly has a good time with a new build around a big man.
