I don't think he's an obvious upgrade. I don't think he's as good as you say. He's alright, but he's not going to make this team leaps and bounds better than what JC provides.
Yeah, you proposed Batum, whom I love, but extremely unlikely. I just think without a stud added, this team will still be lacking.... I don't think Lowry is that fancy fish.
Our wing is the biggest concern, not PG.
