Definitely time to give up after selecting him in the draft, make sure you don't wait until you actually see what happens.
It's all about perception, MKG gets to play the roll of King Golden Dick because his team mashed on people. In reality he's just as much a role player as Barnes projects to be (albeit in a different capacity - slasher/getting to the rim)
Barnes projects to be a role player who can give you 17-21 with a quick release and solid defense but he sucks because he didn't dominate all the time surrounded by 5 other first rounders at UNC (much like MKG).
It's amazing how differently these guys are looked upon when they both project to be pretty similar at the next level (secondary options, glue guys).
In actuality, they are nothing alike.
Wherever this "Barnes is going to be an elite defender" stuff is coming from, I'm not going to totally dismiss it because he has the length at the position to be good on that end of the floor and if he puts in the work, he can probably get there... But MKG is a natural born beastly defender and you could see it the moment he stepped on the floor in Kentucky. I have little doubt that MKG will be an elite defender in the NBA, any position, and probably soon. Barnes doesn't have that kind of ceiling on the defensive end from what I've seen. He may end up being a good defender, but he isn't on MKG's level in that department. Gilchrist is a really dynamic defensive player, be it on-ball, playing the passing lanes, protecting the rim, etc.
On the other side of the floor he does more than just "slashing to the basket." He is a very good ball handler for his position and an above average passer. He also has elite rebounding skills for the 3 position. Basically, the only thing that he doesn't do well on the offensive end is shoot the ball, but he also isn't as awful as some make it out to be. Awful shooters don't make 75-percent of their free throws as a freshman in college. It is the weakest part of his game, but considering he does just about everything else so well, that isn't saying much.
Barnes, on the other hand, is a good shooter, but I don't seen him as an elite shooting prospect. The idea that Barnes' shooting prowess cancels out all of the things that MKG does better is just crazy, imo. Maybe if he were Glen Rice or Ray Allen, but he's not... And he's not close. He makes some flashy, difficult looking jumpers, but he also misses a good bit of the time.
Say what you will about MKG's shortcomings as a jumpshooter, but he is a much more efficient scorer than Barnes and probably always will be. If Barnes was forced into a lot of difficult shots on the college level, it will be even more pronounced in the NBA.
It just still feels to me as though Barnes is living off of his immense reputation coming out of high school, which is amazing considering he underperformed in not one, but two seasons at UNC. I honestly believed that when we got the No. 4 slot, we were out of Harrison Barnes territory. That is the main reason I was so relieved we didn't get No. 5 or No. 6 in that lottery... Because that is how little I wanted Harrison Barnes to even be an option. The idea that Grant and Co. are still zoning in on this guy makes me literally cringe.
This is the way I prefer to look at it:
Ball handling: MKG > Barnes
Playmaking: MKG > Barnes
Slashing: MKG > Barnes
Shooting: Barnes > MKG
Rebounding: MKG > Barnes
Defense: MKG > Barnes
And this isn't factoring in things like being a hard-worker, which may be a quality that Barnes has (I honestly couldn't say), but MKG is renowned for the way he works... And ego, which is one of my greatest fears with Barnes, what with his going back to school to improve his 'brand' and the whole 'Black Falcon' thing.... While MKG seems like a very quiet, confident, unassuming guy.
Please god... Make this a smokescreen.
