Until now, the Ravens offense always ran through Ray Rice. Joe needs a running game and a line that can block. Give him that and it's another SB. So yea...he's a system QB. All the QB's in the NFL are. It's smart. When facing a good rushing attack, defenses have to bring more players into the box. Where Joe comes in is that when defenses crowd the box he can burn them deep because his receivers are facing man coverage. If defenses stay back in coverage, the running game kills them. Well...that is not there now. Joe had a damn good game for getting sacked 4 times, hit 6 times and 30-40 mph winds. He's one of the few who can go into Mile High in December and January and put a hurting on you.
