The real problem with comparing these two is that Losman is a 4th year player while Edwards is a rookie. It's easy to make a statement like "Losman is better than Edwards." But it's not fair to compare a rookie to a veteran with several years of practice and game experience under his belt.
Losman barely played as a rookie. As a second year player he completed 49.6% of 228 attempts for a yards per attempt average of 5.9 and a QB rating of 64.9. Those are lousy numbers. Edwards is playing better than that right now in his first NFL season.
I won't dispute that Losman might be the better passer right not, but that doesn't mean he's the better player and the better long-term solution. Edwards is playing relatively well in the context of being a rookie QB on a mediocre offense. It's certainly too soon to write him off.

Loseman reminds me a lot of a certain QB named Rob Johnson that was run out of town not that long ago. He has the tools but not the brains. How many seasons are they willing to sacrifice for the sake of finally proving, once and for all, that Loseman can't cut it as a winning QB.
You haven't watched a lot of football have you? Losman is NOTHING like Johnson, outside of both coming from California. Buffalo fans like you deserve to have 4 SB losses as your shining achievement. I'm so glad I moved away from that town. Great food, but a TON of lousy people.
I am not from Buffalo and I am not a Bills fan, but I know a loser when I see one. Since 05, the Bills are 9-19 in games that Loseman started. They are 6-5 in games he didn't start. Most of these games were started by the great Kelly Holmcomb and (3rd round pick) rookie Trent Edwards.

No, no you don't. Quarterbacks aren't the only component of winning. There were many games that the defense let the team down, not Losman. Nevermind that the coaching staff in Buffalo is terrible. And you are ignoring that Edwards has ONE TD PASS in his career. The games the Bills won with Edwards had nothing to do with quarterback play.
What was Rob Johnson's record as a starter in Buffalo? I don't know exactly, but it was horrible. Flutie didn't have the stats, but he won a lot more games than Johnson.
I have no idea what Johnson's W/L was, but that has nothing to do with Losman at all. And most of Buffalo wanted Flutie to remain the starter as it was. But of course, you are again posting about what you know nothing about at all.
How many leagues do you have Loseman in, btw? I have neither player in any leagues.
Absolutely zero. In fact, I've never had Losman on a fantasy team. I have however seen quite a bit of Buffalo games, and can tell you with an unbiased opinion that Losman is a better QB than Edwards, not just due to experience, but in terms of talent and natural ability.
