I like your starters. Very solid for a 12 team league.
I also agree with your theory regarding McCoy/Westbrook.
However, the rest of your bench looks pretty thin. I'm sure that's common in a 12 team league, though. But, in my opinion, it was too early for you to take the NYG defense in the 7th round. I'm not sure who, exactly, you passed up on, but I suspect that you could have added some much needed depth at RB or WR. You probably could have gotten a very decent defense several rounds later and had less to worry about at your other positions. Besides, DEF is kind of like closers in fantasy baseball, every year there are a couple of defenses that come out of nowhere and can be grabbed up for free off the waiver wire early in the season.
On the other hand, well played waiting til the 14th round for a TE (if you miss out on the Whitten/Gates/Clark/Gonzalez run, there is very little difference between the 5th guy and the 12th guy) and waiting til the last round for a Kicker.
As i said, your starting lineup looks good, I don't see any glaring holes. And I don't see any trade-bait on your bench, so I say stand pat heading into the season, you should be in good shape. But scour the waiver wire looking to add some depth in case of injury....and for those pesky bye weeks.
