I'm having the same issue. HUM sliders, esp QB, don't need to be adjusted too much IMO. It's largely based on the users play. If you play the game with the intention of making it as sim/realistic as possible, then more often than not you won't have those huge passing games. 40 attempts is way too much for a HUM QB - With a balanced offense I'd say anything around 35 and under is a good figure.
