Well... hardly an expert like some on here, but I'll throw my two cents in, I guess. Definitely liking QR, so that seems a must.
I think Natural Leader could be good, if you've got a lot invested in Field General and your team's been struggling with Morale(I've seen issues with WRs and low morale, even when winning and having great games..).
If you're outlevelled by a good amount in a league, what do people think about Clever Instinct(Assuming you have a pretty high Pump Fake)? I can't remember ever hearing it mentioned, so no idea if anyone's even tried it.
I know Big Heart still helps a solid amount. I'm not really sold on Hard Count, personally. It seems like too little a gain for too many VA points. Clutch, kinda similar. It's so hard to quantify what actual effect it has where and when.
Would think, if you're behind late a LOT, a combination of Big Heart, Clock Manager could create a Joe Montana type of beast. I'm not sure why Football Genius and Laser Arm couldn't still be useful. If you have at least 70 in either, and you drop a fifteen in FG or LA, that's at least 5 skill points. I'm not entirely sure, though... I haven't really figured for sure at what point your QB is probably set on Throwing(105+, 110+, more?) and might think to look at Vision/Strength(Depending on your preference) or Confidence, SAs, etc. That's a whole different discussion, though.
