Good points, but I respectfully disagree. No need to bring in a guy who could challenge for the #1 job. But it never hurts to bring a veteran who has WON GAMES IN THIS LEAGUE. Look, the Losman pick is for next year or maybe the year after. We can't put JP in and expect him to win games for us this year, afterall he's a rookie. I almost feel the same way about Travis Brown with his lack of experience.
And while TD does have plan in place for the future (and a great plan IMO with Losman waiting in the wings), he also has an obligation to ensure that we are covered for the current year. A guy like Shane Matthews doesn't cost a whole lot and he knows what his role is. Afterall, he was the #2 or #3 QB last season with Cincy! Bringing in a guy like him or Jeff Blake, two guys who have won their share of games in this league, can't hurt. In fact, I feel it can be a great help to know that if/when Drew gets injured, we have a capable backup.
Just my 2 cents.
