i don't think jp losman worked at all close to hard. it has been mentioned by ex teammates of his that he is not a team guy. in think he is lazy and slow, and never once put in the very large amount of work required to be a good nfl starting qb, let alone make up the extra distance he was behind he curve to start.
bill in nyc -- wow, i knew jp was trash (worst qb to ever get 30 starts) but i didn't think it was THAT bad. as we all know, a qb can lift an entire team, or bring one down. jp losman couldn't even just be a guy, he always brought the team down.
