NFL - Sixth Sense, but he doesn't post here much anymore. His write-ups are awesome, very inclusive of statistics, situations, and fundamental capping angles.
MAC conference CFB & CBB - Kodiak7 He thinks he knows Big 10, but he's got the MAC pegged.
CFB - last year NYReb's 10* picks were $$, and if he ever had a 15* pick, mortgage the house! This year he really slid downhill, not sure what happened. I think he's doing well in NBA, but I don't follow NBA.
Many others have had good runs in certain conferences, etc., but those are the ones who really jump out in my memory.
