This interview from Pro Football Weekly actually took place before the rumor mills started about Larry wanting out of Arizona at the end of the season. So while that isn’t directly addressed, Larry doesn’t give the impression he is extremely unhappy…but he doesn’t seem extremely happy either. He’s basically just saying the right things the whole time, so you can take that as truth or as just athlete interview speak.
Go ahead to the link above to read the interview, but it doesn’t offer a lot of insight on whether or not Larry is really happy. It does give a look at how his relationship with Leinart and Boldin has grown though, and that may be a factor in him staying in Arizona.
