Just adding what I've seen so far...
I play on custom sliders, that are pretty much between All-Pro and All-Madden, a bit more towards the All-Madden side of things. I'm now 9-3 with the Browns, and have had MANY drives stall because of a wide open drop. One game in particular, my receivers had TEN DROPS in one game. I mean, statistically. Brian Robiskie alone had 4 drops in that game.
As you can see from the record above, I'm 12 games in. Braylon Edwards (and I know he led the league in drops last year, so I expected a high number, but...) has 17 drops in 12 games to lead the league. Robiskie has 13.
As far as only completing short passes, I feel that pain as well. Really the only time I get any long pass plays are when I complete a pass anywhere from 3-7 yards deep, and they happen to break a tackle or manage to get a block. I MAY have had 2 or 3 deep passes work so far, and one of those actually bounced off the defender's hands and into Masseqoui's.
Not complaining, though. I know I shouldn't be 9-3 with a team like the Browns, but my stats are pretty realistic overall (outside of the tackles issue, and small yardage totals for the WRs), and every game I've had has been close and challenging. The only ones that weren't close were me getting blown out by the Ravens, and the Vikings riding an unbelievable 25 point 4th quarter to a 38-28 win. Pretty happy overall thus far.
