I'm sure other schools have their stories, too, but it seems like we have succeeded more with Plan B guys than anyone out there. There are very few recruiting battles we lost where we didn't end up winning (or turning out ok) in the war. Whether it be major spring pick-ups (Donyell, Khalid, Emeka, CV, Thabeet) when schollies were available from others not taking them, or getting Kemba when Jennings fell through, or Gordon when Torbert fell through, or Bazz when Knight/Joseph/Selby fell through, we almost always land on our feet.
Even something like losing Kevin Durant, who would have made a huge difference that one season (we sucked) was a short term hit, but not necessarily a long term one. We weren't going to win that year anyway, and we were able to give those minutes to Sticks, who later helped us to a FF. Or going back to Jason Williams - he would have kept us out of the NIT in 2001, but might not have played beyond that year, whereas freshman Taliek was able to go through on the job training and then win 18 postseason games in the next three years.
Ellington over Dyson perhaps is a Plan B where most would like to go back in time and have Plan A work out - but we don't know how 2009 ends with both players healthy (or whether Ellington comes back for his senior year in 2010 when Dyson struggled).
