Roethlisberger is not the same player he was after the accident. I think he lost his mojo or aura, if you like, after the crash. Hopefully he can get back to form because hating on him now is not fun.
Losman will end the year as the starter, he'll start the next year as the starter, if he doesn't show improvements I can't say how much he'll last as the leader of this team, hence we won't be drafting any QBs with our 1st or 2nd round picks.
