More reason to go BPA. If you’re letting fit get in the way, you’re assuming the two things go right. If that happens to be the case….well damn how terrible it must be to have two good players. Just like you can’t predict BPA, you can’t predict that the guy who “fits” will actually pan out. With no guarantees you shouldn’t let fit get in the way of taking your best shot unless the situation is very established.
Unless you want to go forward with Sexton and make him a cornerstone, the Jazz don’t have anyone on roster that should prevent any kind of player from being drafted.
