I'm in a similarly-scored league (0.5 PPR but with 2 WR rather than 3), and I'd be happy with your team. I still think SJax has one good year left in him, Murray should be the focal point of the offense, and the Wells/Williams picks save you in Arizona. Ryan is obviously being pushed as primed for a big season, and having had him the past two years, I can say that even if he doesn't explode, he's still very consistent in the regular season (particularly at home).
I'm guessing with the 3 WR requirement, people went on runs for receivers early. Even still, I like Cruz and Maclin. Britt is obviously a week away from playing, but at his ADP, it's very likely he'll be a huge value.
I agree that TE is probably the one weak area. I'm guessing someone already grabbed Rudolph, but if Bennet, Housler, Cameron, or Allen is available on waivers, might try taking a flyer on one to see if they pan out at some point.
The only other potentially shaky area could be your WR3, although between Britt, Young, and Moss, I'd imagine at least one will work out.
All in all, I'd say it looks like a solid team. Especially if Wells or Williams start doing well and SJax looks like he'll hold up, you could consider a package deal with them down the line for a solid TE or TE/WR combo. Given how thin RB is this year, I don't think you'll have much trouble finding a taker.
If you have a chance, feel free to swing by and evaluate my team, particularly given the similarity in our league's settings: http://www.fantasyfootballcafe.com/forums/viewtopic.php?f=44&t=517699
