Why Not Henson?

Reports this week had some Browns officials scouting Drew Henson for the sole purpose of giving him a ranking in the upcoming draft. I have to wonder -- why not scout him with the intention of making a deal for him? There would be a certain logic to it....

Assume the Browns resign Couch to a two-year deal. Or Couch is let go and Holcomb is the starter for a year. In either event there is a need for a future quarterback. Considering that Henson could perhaps be had for the Browns second-round pick, I think the team should be seriously evaluating Henson. Might be a good way to get a 1st-round talent for a lesser price.
