Trading Love for George does anyone for us that bridges the gap between us and GSW, getting us closer to more titles;
1) Adding George would make our offense that much more dynamic - we add another guy who can get his own shot off the dribble, and drive and kick - which is so important in today's NBA. You just can't have one guy on the floor who can get penetration, like when LeBron sits with Kyrie. This leads to a lot of ISO-ball. Love can do two things, and it's post up and spot up. George changes that and makes us much harder to defend because he can do both and more. We can move to more of a passing style offense, and allows us to play much much more free flowing and position less.
2) To that point he vastly improves us defensively, especially with reference to GSW. He can switch every screen, and play valuable minutes on Durant or the other teams best player that gives the King ultra valuable on floor rest.
3) piggybacking off that point as well, he allows LeBron to get ultra valuable off court rest as well - by holding leads by giving us that more dynamic offense. He also would allow us to win regular season games without LBJ with much more regularity - ask yourself if you swapped Love and George on the Pacers are they even a playoff team? He'll no.
4) this is most important. It vastly improves on our championship window. A core of George/Irving could likely compete in the East now without LeBron. As he ages he will need the support players to provide much much more than what they can currently. The proof is in the cards guys. Awful regular season without him and huge (-) deficit with him off the floor.
Listen, I really do love Kevin Love. He's already cemented himself as one of the greatest Cavaliers ever imo. 0 will hang in the rafters one day. However, I won't let my love for Love cloud my judgement when it comes to getting better as an overall basketball team, and George just does that.
