"Does your farm generate an inpact player in the major leagues every year?"
Not many teams do this every year. Maybe you can say the Marlins with Willis,Beckett,Cabrera,etc.. but who esle? Teams like the Padres and Rockies are always ahead of the Reds when the Reds have had some impact talent every year.
2005-Lopez-He did play some years in Louisville
2003-Ryan Wagner was pretty solid with a 1.66 era although it was only 17 games.
2002-Kearns he Ops. 907 Reitsma also had a good year starting 21 games with a 3.64 era
2000- Larue came up around this time altough he didn't produce that well
1999- Scott Williamson was the NL Rookie of the year
So the Reds have had some talent come from the minors, everyone wasn't drafted by the Reds but they did play in the farm system. The scouting department has been pretty good though considering they picked Sowers,Markakis, and wanted to draft Kazmir.
