Lets not pretend it was cheap or free to bring those guys in. What will we have to bring their replacement or the next guy who wants in? That's where 4 picks hurts. We very well could end up in a situation like the Lakers have been in post bubble. All the money is tied up in 2-3 players and unless another team is willing to give someone away, we can't bring them in because we have nothing to use in a trade.
FTR I've come around on this trade a lot since it happened and I was initially pessimistic but I'm not 100% sold yet. I still worry some about the future and the cost involved here. This has to work or there isn't a viable plan B. The Suns went all in on a full house and usually that will win the pot but nothing is guaranteed and there's still a chance someone else's hand is greater. I don't mean someone else makes a bigger deal, I mean they beat the Suns for the title or the Suns don't make it there for some reason.
