Believe it or not, the probability for a 0-rated tackler to tackle a 100-rated break tackle player is still 95%. I don't know that I want to go much higher than that.
I'll look some more at the kickers, your kicker definitely shouldn't be missing extra points like that. I'll see if I can't push something to improve the kicker accuracy before the first regular season game.
For the QB decision making, if you're talking about Fortney his field of vision is very low, which is going to mean that he probably is going to lock onto his primary receiver and not see the other open players around him. If it's Perkins, he should be a bit more likely to throw to a better player. One thing to consider too is that if he's under pressure the throw could be a throw-away, at this time the play-by-play doesn't differentiate that.
On the issue of the cutback runners and kick returns, I agree that those are not where I want them to be and am still working on them.
