The Football Blitz

Are there any college football dynasties left?  FSU at one time could have been a dynasty and will Jimbo Fischer be able to restore FSU dominance.  There are so many things that affect the college game these days it is hard to stockpile the talent.  Look at USC, Oklahoma, Florida, etc.  These are modern day dynasties, but not at the level it was previously.  USC and Florida would be the closest to dynasties currently.  Can they sustain it?
