I read this article also along with Walshs' comments in which he states that almost every championship team has to have a BIG MAN. With this in mind and given Walshs' experience I believe that he knows what it takes to compete for a title.
That being said I can't imagine ANY scenario that doesn't involve a superstar like Lebron or Wade or whoever and a quality big like Bosh or Amare in NY.
The league needs this. If you can recall across all sports once a rumor starts and keeps going on and on it usually happens. It happens with the Yanks, the Giants etc... . And its not just who they acquire it's the rumors about the moves the resignings the rookies on their radars. I find that once the "word around the league" keeps getting more and more momentum it happens. Its just not confirmed until the deal is actually done.
Recent rumors (that actually happened):
Firing I Thomas
Trading Z Bo and Crawful
All of which were rumored before they happened and actually happened.
*There is a rumor that Stephon Marbury will be gone by the deadline.lol lets see if this happens.
I know not all rumors come to fruition but I've noiced the ones that don't go away or when nothing is done to dispell the rumor it usually holds true that something close to the rumor is going to happen.
NY will have at least 1 superstar/allstar suiting up in 2010. And definitely a big man too (maybe before then).
