Familiarity shouldn't hold up getting an All-Star ultra scorer. What stat happy fans ignore is the toughness that Gibson brings and even more so Butler. You can find guys to replace the stats Gibson puts up but there are few if any who bring the determination game in and game out that he does. You know in NASCAR they used to call Dale Earnhardt sr., The Intimidator' because he would wreck you to beat you and wasn't afraid to say so.
Well you can see in Lebron James a guy who intimidates most opponents but the Bulls have Jimmy Butler who stands up to him, way better than Loul did. And Gibson is the same way. Did you hear that stat at the end, first time in 4 1/2 years James did not shoot a free throw in a game, an OT game to boot.
For all that Anthony can do what he isn't is tough, not the way Noah, Gibson and Butler, even Hinrich are. And pay attention to your coach, Thibs counts on that toughness. So yes you want him because he can score but you don't want to cut the heart out of your team or you're not gaining as much as you need to get over the top.
