Schaub did not play like Flacco. Schaub threw two picks and one of them was worth 6 points for the other team.
Im not saying Flacco doesnt throw picks. The difference is
1) you treat Schaub's picks like an inevitability. you sit there the whole time just wondering when theyll come
2) When Flacco throws picks its usuall because his line cant protect him, and/or his receivers are bad, and/or its late in the game, he's out of options, and has to try to make the game winning play.
Schaub just makes dumb decisions.
