If from what i hear is true and the Lakers are really willing to give up Randle and the number 2 pick then saying the Celtics have the most to offer is absurd.
I also wouldnt do any deal for Cousins involving Marcus Smart. The most i would hope Danny would do is something like Sullinger + Wallace + Young + 16th + Zeller + Brooklyns 2016 1st, and that still doesnt touch the Lakers offer.
Smart is good, but he'll never be as good as Cousins - if adding him to the deal is enough to make it happen, then I (and Danny) will do so without hesitation.
Also the only valuable asset for the Lakers is #2, so the importance of that depends on how much the Kings value draft picks - which (according to reports) is not all that much.
If the reports are anything to go off, then I would assume that the player(s) would have to be the primary component in any deal, and any draft picks would just be added as a sweetener.
Now from what I see, Randle has significantly less value than Smart because:
1) He is significantly undersized
2) He's a one-dimensional player
3) He has a significant medical history and is coming off a season ending injury
4) He was taken one spot lower in the draft (not that important, but just saying!)
So if George Karl's aim is to get proven players who can help him 'win now', then neither the #2 Pick nor Randle, is of much value - since neither has managed more than one game of NBA experience and neither has proven anything.
On the other hand, the Boston Celtics just made the playoffs behind the play of guys like Marcus Smart, Jared Sullinger, Avery Bradley, Evan Turner and Kelly Olynyk. Those guys might not be stars, but they have all proven (over at least one full season) that they have NBA ready skills and can help a team win.
If the reports are true about what George Karl wants, then all of those guys have greater value to him than a prospect who's never played, and a draft pick.
