It depends how much demand there is for the pick. The player I want us, as a fan of the team, to pick is LaMarcus Aldridge. Though, I believe that Andrea Bargnani could also be the pick. However, we could also trade down for a point guard like Marcus Williams.
If we stay at the 1st overall selection, I would like LaMarcus Aldridge. He likes the city and is good friends with Chris Bosh. Bosh, Aldridge and Villaneuva would give us three solid young big men.
