I didn't think the Cooper article was that bad. Len at #5 is not a bad move, IMO, assuming our training staff gives a thumbs up. This draft has lots of decent bigs and I think we would do well to draft three of them if we could pick up a couple more first round picks. Bigs take longer to develop so getting them early in the rebuilding process is a good plan if you can do it. I also agree that Gortat and Scola should go - heck, I think O'Neal should, too, because we don't want to win many games next year and they do not fit with our rebuilding time table. Markieff, Haddadi and two rookies being our frontcourt should accomplish that.
Personally I want them to draft Oladipo at 5 if he's available - this is more about the delight I take in watching an elite perimeter defender doing his thing. I enjoyed the heck out PJ and he's not elite - Gordon Hayward showed that all you have to do is make good use of screens and you have little troubling scoring on him. (I would tend toward using PJ to defend 'stretch' 4's - he gives them fits on the perimeter and he'd be able to cope with them down low surprisingly well, too. It probably wouldn't work so well in the playoffs when teams could adjust to take advantage of his size.)
Trading our 2015 first round pick for Dallas' #13 pick this year is not a terrible idea. I do it a heartbeat if we could draft Dieng with that pick. I suppose if the 2015 draft is known to be 'loaded', we should think carefully about it but if its not why worry. I think we'll be somewhere in the #10-15 slot range by then, having great faith is our new FO - and two years headstart is worth quite a bit. If our old crew was running the show this year, I'd want to hang on to future picks for dear life.
Where I disagreed violently with Cooper was bringing in JJ Redick and Jackson - they could well hurt our draft pick in 2014 and they have little value for the future beyond that.
