I don't necessarily disagree, but if you look at the Suns' composition, you could see how they could fall into a similar trap. We have a bunch of guys that aren't necessarily great fits around Booker (with the exception of Jackson, I think he's the right guy if his trajectory continues).
We have one or 2 more years before a series of contract extensions (Len, Booker, Bender, Chriss, Ulis) will more or less lock our rotation in place. I assume one or two of those guys - maybe even 3) will get cast aside, but with Warren locked in and Knight on the books, it's going to get expensive real fast.
Will the team get over the hump by then? Or will they be stuck in mediocrity where they are good, maybe even great, but not contender status. Obviously it's waaaay too early to worry about this as lots of things could change, but I'm not sure I have the confidence that McD has the know how to not land the Suns exactly where the Blazers are now.
That's my long term worry right now, as irrational as it probably is.
