I would keep shaq. The biggest issue with shaq is that he alone can lose you the FT% category, but, he can also grab you the FG% not to mention some dimes coming out of your center slot.

For more information on how some of the players stack up against each other, i compared a variety of players in all the pertinent categories in an article at the end of last year. See the below link.
