You can't say 'they didn't have those kind of players' when Pop is the VP of the organization and actively went and signed up both Bonner and RJ. Not only we overpaid for those turds, we overplay them too. This roster was put together by them. You can't remove responsibility from them.
As far as 'Score the ball', you need balance. You can score a lot, but if you don't have at least some defense to fall back to when the ball isn't going in (inevitable), or when you really need a stop, then you're no better than SSOL. Considering we have basically no decent perimeter defender, and that you don't want to sit Manu or Tony, you can't afford not to have two good interior defenders, especially when one is on the decline (or two, if you count Dice). This was somewhat masked when Bowen was around, but now that he's gone, you can't hide from it.
I also want to add that Bonner isn't the only problem. He's just the most obvious weakest link, and has consistently been since being given meaningful minutes.
