Agreed, something really weird had happened to me on the Madden 12 demo to me today, I had the Packers beat pretty much 10-14 with 1 second left on their own 20 or so yard line, the Packers lined up with 3 WRs on the left and 1 WR(Greg Jennings) on the right, well after Rodgers dodging a Peppers sack he lofts it up to Greg Jennings and is ended up tip in the air and eventually CAUGHT by Nelson and taken in for a touchdown, I ended up watching the replay and noticed the 3 WRs as SOON as the ball was thrown were at a dead sprint toward Greg Jennings as well as my CBs and Recievers which is completely unrealistic.
I know the Broncos had done something similar in real life but the recievers(Marshall and Stokley) were on the same side as the hail mary throw and didn't sprint to the other side of the field as soon as the ball left the Qb's hands.
