I bet the Lakers do what they can to trade up to take Simmons, short of offering Russell (offer Clarke?). I think they see him as the next Magic Johnson, the return of Showtime.
Then Philly would hold the pick at 2, and offer to let us take Ingram so long as we give them Rozier plus Hunter. That way they can take Murray at 3.
If something like that were to occur, I could see Danny going for it, as you could plug Ingram into our line up pretty fast. That is unless Ainge feels that he likes the long term prospects of Bender better. I doubt that is the case, but it is possible.
Wild speculation, but fun to think about!! I am such a draft junkie!!
