I was looking for a tool that for example would allow one to pull up a list of all players in 2008 that hit 20+ HRs, had 10+ SBs, and hit 0.280+ or whatever set of criteria you might establish. Rotochamps used to have such a tool with their stat wizzard, but it seems their site has undergone an overhaul and seems to be offline for now.
C- Santana 1B - Huff 2B - Wigginton 3B - Longoria SS - Tulowitzki OF - Posednik OF - Suzuki OF - J. Upton DH - Lind Bench: C. Pena, Morneau, Prado, Bay, Barmes SP: Oswalt, Hammels, Nolasco, Weaver, Shields, Lackey, Vargas, Volquez RP: Soriano, Perez
in excel just sort and do something like selectively highlight players that meet certain criteria or gray out players that don't. not exactly as jazzy as a web app would be, but you can manipulate the stats any way you want
