I agree that Paul is better than Rondo. But a few things to consider:
1) Can Rondo eventually be better than Paul?
2) How much more than Rondo would we have to give up to get Paul?
3) Can Paul seamlessly transition in to this club this year and win a title THIS year?
4) Will Paul stay here beyond 2012?
Number 1 no one really knows. I'd probably say no, but you never know.
Number 2 is tough. Outside of Baby or Perk, what else would they really want?
Number 3 is extremely important, as if we don't win a title this year, we very well may end up being New Orleans in a couple of years.
Which leads to question 4, being that while the Summer of 2012 could be the summer that Paul lobbies for someone to join him in Boston, it could also be the summer he pulls a LeBron and jets to NY or elsewhere.
