The Bobcats had nothing to lose with this trade. It may not have returned them first round picks or young stars, but it will succeed in losing them nothing.
The salaries actually weigh out to save the Bobcats a few hundred thousand dollars (after salaries are prorated for the remaining time) and it lasts only until the end of this season so nothing risked on this end.
Hakim Warrick found himself in and out of favor during his short stint in Charlotte, arriving in a trade with New Orleans for Matt Carroll. Initially he saw little playing time but after Tyrus Thomas and Byron Mullens had to sit out for extended periods of time with injuries, Warrick saw more minutes on the court.
He started 14 of his 28 games for the Bobcats but was replaced in the lineup by Jeff Adrien and Byron Mullens and eventually became inactive for the team. He had a handful of good games, most notably scoring 18 points against Miami and 16 against Boston.
But Warrick became unpopular because of offensive inefficiencies and utter lack of awareness on defense. His passing is poor, not that you're likely to see him pass often. If given even the slightest daylight, Warrick was more than likely going to use it. To his credit, he can hit shots from pretty much anywhere. Maybe not efficiently, but there's always the chance he can make them. His shooting efficiency percentages are at career lows.
Defensively, to say he lacks awareness might be putting it lightly. He watches the ball a lot and loses his man and doesn't box out. This lends to his poor rebounding and sure didn't help the Bobcats, who are one of the worst teams at defensive rebounding.
Ultimately, Bobcats fans watched Hakim Warrick have the worst season in his career.
So the bar is set quite low for Josh McRoberts.
His time in Orlando was about as memorable as Warrick's in Charlotte, posting his worst field goal percentage in his career. His playing time has also been inconsistent as the Magic have had to utilize him more with Glen Davis' injuries.
To be sure, McRoberts is no savior for Charlotte. He does nothing spectacularly well, but is one of those somewhat versatile players with a wide skill set. A "jack of all trades, but master of none," one might say.
His rebounding percentages are slightly better than Warrick's, even in McRoberts' down year. And even in this horrid shooting season, his shooting percentages are right around Warrick's. But McRoberts is five years younger than Warrick and has shown he has room to improve. McRoberts had a couple solid seasons in Indiana and perhaps a change of scenery could do him good.
In essence, here is Josh McRoberts. The 6'10" forward is a high flier who can also be a nice option a la Byron Mullens with pick and pops. Because of his low usage, he's fairly effective. He's a pretty decent passer for a big feller, he can face up in the post and he doesn't take a lot of shots. But with this versatility he can at times try to do too much, leading to turnovers. He's no great defender but he's also no Hakim Warrick. He's practically Byron Mullens Lite.
As far as how he'll fit into Charlotte's lineups, it looks like he'll be backing up Byron Mullens at power forward, with the capability of playing center in small ball situations.
He's an upgrade over Warrick at no extra cost, so what's the harm?
