Because when Manu was in his prime, he wasn't just a "good player off he bench". In 2005 he was unstoppable, and a force for the spurs. I shouldn't have to explain this to a spurs fan, Marco belinelli is not and never will be a Manu ginobili. Now maybe I misunderstood the post, maybe we are asking if Marco can be manu from last year. If that's the case then I think he could.
But the title of the thread was "is belinelli the new ginobili". If that's the question, the answer is a resounding no!
