There are definitely issues in the way Madden handles the deep pass, as well as the coverage system...
I looked up deep pass stats on PFF and the top 10 QB's were between 43% and 60% which makes sense because the attempt at the long passes was between 9% and 16% of passes tried with an in air travel distance over 20 yards; thus suggesting to me that deep passes are attempted when the odds are well in the favor of the passer to receiver to complete the pass.
What I also found interesting on the same page was the completion percentage of QB's when considering passes that were on target but dropped...When the "drop" is considered in, the QB completion rating is between 74% and 80% for the top 10 QB's...This statistic has me considering that the reason Madden sees so many higher than average completion ratings is because receivers catch too many passes; they are not catching "a lot" more than they should; I believe we are talking maybe 2 or 3 balls a game or so that should be drops..
