Woah there. The thing I enjoy the most about this place is that everyone can debate light-heartedly without taking everything like a personal criticism. If you think " ...MARTIN = HAYWARD?! REALLY?!" equates to mocking you, then boy, there's a LOT of rule breaking going on here. Anyway, to get to your other points:
With Rubio and Irving, it's not controversial that Rubio is better. However, the difference is not that big which gets back to my latter point that one-on-one comparisons are very flawed. The Lopez/Valanciunas comparison will definitely boil down to personal perspective, because even if we isolate the sample size to present production, I think Valanciunas could post similar defensive numbers with Lopez because of the aforementioned belief that Val utilizes his defensive potential better than Lopez does. Besides the point, I'm not disagreeing with you that NY has the better defensive staring lineup, but the difference isn't as big as you make it seem. Furthermore, when factoring in the overall roster, I'd give the defensive advantage to Boston.
