Without hindsight, which obviously shows SGA as the right pick there, I would have taken Michael Porter Jr with that pick. With hindsight, I'd probably rather have him than Kyrie? Unsure. Hard to imagine how everything else plays out... does IT stay and get the brinks truck disabling us from signing Kemba? Does Rozier have a great 1.5 seasons and get extended? How has the team looked?
In a vacuum, if the question is "Would I rather agree to a 2 year rental of Kyrie or have Collin Sexton on a rookie contract plus RFA rights?" then the answer is 2 year rental of Kyrie. Even as maddening as he was, Sexton is that bad.
