Well, I don't necessarily believe it, but it makes a lot of sense.
I actually think a trade of Randolph for Andre Miller and Willie Green would be good for both teams (maybe the Knicks could also throw in Temple Alum, Mardy Collins).
This allows the Sixers to hand the PG reigns over to Louis Williams (and they can bring in a veteran to back him up), and gives them one hell of a talented (and exciting) starting lineup with Williams, Young, Iguodala, Randolph, and Dalembert. Collins also still could end up being a decent compliment to Williams.
This would be especially good, because it would allow Iguodala become a true second option on offense, where he belongs.
For NY, it gives them some nice cap savings in Miller, so they can move closer to getting below the cap for Lebron, and it also helps to solidify their PG position for the next couple years.
