If it was only one game then don't sweat it. I just threw a 3 interception game with flacco. It happens sometimes.
Deep out or quick out?
The deep out is one of the hardest and most dangerous passes to throw, both in Madden and in real life. Teams are calling fewer and fewer out routes because of this. Personally I love them and if my WR has a favorable matchup I throw the deep out frequently. It is not broken but you have to be careful.
