So far at most Danny has only been able to paint a picture of two young stars--whether DH and CP, DH and RR, or whatever. The right PP deal could change that.
IMO he needs to pull off something like the prospect of somehow landing both Kevin Love and DH, or at least two more legitimate forward-looking All-Stars to go with Rondo or Rondo's All-Star level replacement.
No need to get into deeper the history of Boston navel gazing. If he springs the team free of the ghost of the Big Three, which no young studs want to attach themselves to, and can pull off a beauty of a trade and FA signing or two beautiful FA signings or whatever, the C's are on course to a strong future. Inching toward it with mediocre role players or just one additional All-Star slot would be a killer IMO for what Danny needs to do.
