I think Pat is a lot better than he's given credit for. He's not great by any means. But, I believe that if given a consistent role with the team he could provide at least 80% of what Evan Turner provided us last season. And 110% of what Aminu provided us. Like I said - not great. But given his salary, I'd rather have him on the team and get rid of Turner*/Aminu.
*For some odd reason, I'm slightly hopeful that Turner will be good this season...or at least significantly better than he was last season. I have no reason to feel this way, but I do.
