I discussed this topic with Section roughly a year ago. I said I always wanted Jimmer to take wide open transition threes. If I recall correctly, Section said he would prefer that Jimmer slow down and wait for the rest of his teammates to join him given the likelihood that the Kings would not recover a rebound if Jimmer missed the three. (Section, please let me know if I am misrepresenting your stance.) Prowse, Casey, and I revived this discussion yesterday.
Here is the scenario: Jimmer has the ball in transition. He has three obvious options. He can: (1) attempt a transition three pointer with the understanding that the opposing team would likely recover a rebound; (2) take on a transition defender in the hopes of converting a difficult layup and/or drawing a foul; or (3) hold onto the ball and wait for the rest of his team to catch up before setting up the half-court offense against a composed defense.
Jimmer is a great foul shooter, but I still prefer (1). I think it would be relatively easy for a transition defender to disrupt Jimmer's layup attempt without fouling him. Besides, like, he is on this team to shoot.
