I think he means none of them can play PF, which if I'm correct he's totally the right about. They're spacing is going to be downright terrible. Rondo at the point and Cousins/WCS/Koufos as the main big rotation? Ugh, that's really gonna hurt to watch sometimes.
In my dream scenario, Cousins finally has enough by mid-season, demands a trade, and were sitting right there waiting. Maybe Sullinger can put up 17-10 over the 1st half of the season or KO breaks out playing next to Amir. By that time the Brooklyn pick will be showing it's likely value by then (which will be top-10 or better, IMO) and that can be the start of a trade package. Still probably have to give up more, but if the stars align I think were definitely right at that top of the list because we can make a number of interesting packages, Cousins would likely wanna play here, and we could still have a team and coach good enough to surround him and compete with after the trade that someone like say Philly (Our biggest completion in terms of trade assets) doesn't have.
