Augustin is only 23, though. He had a terrible sophomore year, which brings his career numbers down, but being about 3-4 years from his prime, he has the potential to be an above average starter. I'm not a huge Augustin fan, but his production and age are a little promising.
The problem is that one of the biggest things that I have heard discussed regarding the new CBA and one that analysts think the owners will win, is that there will be a Hard Cap. Sure, it may not happen, but if it does, then having Roy will mean not having some other player regardless of what Paul is willing to spend.
I don't think all or even a majority of the owners want a hard cap as it would seriously impair the ability of teams in large markets like New York or LA or those with billionaire owners to leverage wins with their ability to spend; there are some truly big spending teams like Dallas, Orlando and the Lakers that would be at a serious competitive disadvantage if a hard cap goes into effect. Although I suppose some mechanism might be written into the language of the new CBA to give such teams an ability to gradually pare down payroll.
It'll be interesting to see what he could do with talent around him. Since coming into the league he hasn't had much to work with outside Jackson and Wallace. **edit** Raymond Felton is thriving in an uptempo system. His assists went up from 5 to 9 and his per from 15 to 19.
