Knight fell that far, because a number of scenarios magically occurred to create the unlikely situation of him slipping.
1. Utah decided to go with a big. Utah could have taken Knight at no.3, but they decided to go with Kanter. I don't consider this to be an indication that Utah wasn't interested in Knight, they just felt that being so high in the draft that it would be prudent to come away with one of the few quality bigs, and possibly the best big in this draft.
2. Cleveland obviously, wasn't going to take Knight at 4, after already getting Irving at No.1. However, their selection of Tristan Thompson is what really caused this whole thing to happen. This allowed Jonas Valanciunas to fall right into Toronto's lap. Toronto made the same decision that Utah did. They went with a talented big man, hoping to hit the jackpot.
3. Washington, is not going to take another PG after getting Wall last year, which allowed Knight to slip all the way to 7.
We could have had Knight at No.7, which just a week ago would have been considered an almost impossible scenario. Any talk that anybody is hearing regarding "We wanted Jimmer all along, and would have taken either Walker or Jimmer instead of Knight" is just pure spin zone material. The Kings got caught with their pants down plain and simple. Man, what I would have given to see a live camera into the Kings draft headquarters when the name Tristan Thompson was announced. That pick basically was the domino that triggered the whole thing. Toronto was supposed to take Knight, because they thought that Valanciunas wouldn't have been available for them.
This was a clusterf*ck of titanic proportions. Anything we are hearing to the contrary is nothing more than spin. Petrie should have had a contingency plan for something crazy like this happening. He should have had an out. You can't look me straight in the face and honestly say that Petrie wanted Jimmer more than Knight. Sure, he wanted Jimmer alright, but he didn't think there was any chance that Knight would have been there, which is what everybody else on these forums thought last week. Nobody even thought there was a slight chance, so nobody really entertained the idea of Knight in a Kings uniform. This was a grand miscalculation, no other two ways about it.
