For me I guess the problem would be this.....Barnes was the better player when they were drafted two years ago, he's the better player now, and he will be the better player in the future. Any time it was suggested we draft Barnes (because UNC fans knew the talent he had would translate well to the NBA) all the ABC-ers said we were just looking at it through our "Heels-colored glasses". Now here were are two years later talking about swapping picks (Barnes/MKG), giving up a 1st round pick, and an expiring contract just to get a guy who we passed on already. I'm a Barnes fan and I'd love him here, but I would honestly lose all faith in Cho and the front office (the little bit I have left) if they made that move. Not to mention it's looking like they missed on Zeller, too.
If we're really talking about packaging MKG then I think him plus BG is plenty. They're adding a raw talent in MKG, who can help them defensively and they're giving up a player in Barnes who is their 6th man.
Yeah, that angle doesn't bother me much because I'm used to our franchise making huge mistakes in the draft and then spending the subsequent years trying to fix what they messed up, lol. We've done it for our entire existence - outside of Kemba.
So, that's why I would be all for it.
As far as what we did that draft... I didn't know that I wanted Barnes that high per se, BUT I knew with certainty that I DID NOT want MKG. So, to me, anyone other than him at #2 - Beal, Barnes, whoever - would've been an exponentially better pick.
I've probably mentioned here before, but I was actually in school with HB both years, and I was actually disappointed in how he had performed while there. I wasn't sure he was going to be able to do what he did in the playoffs last year. I knew he had the ability, I just didn't know if he could do it. BUT, again, when it came to the draft, I much rather would've taken him to find out if he could rather than take the risk of drafting MKG and his non-existent offensive game.
I just think that MKG's performance thus far has shown that for as amazing as he is defensively, he will never significantly improve enough offensively to justify that #2 pick. He's essentially Stacey Augmon.
