Is Andrew Bogut a top 5 PURE center in the nba?

It'd be interesting to ask this in a years time when he's had more of a chance to get over his injury. He improved his rebounding and defense this year and has great court vision but his offence has suffered. If he can get his offence to the standard of last year or improve then he'd definitely be amongst the best. Probably will never be as good as Howard but can rival Gasol and Noah and Bynum if only cos Bynum is so injury prone (I appreciate the irony of calling someone injury prone when talking about Bogut). Lopez is extremely overated. Can't rebound, can't play D - he doesn't deserve to be in this discussion and Horford is a PF as opposed to a true centre which the question asked. Bogut is right up there and if he rediscovers his offence, top 5 for sure
