From ESPN's John Clayton, more on Drew Henson (some team will pick up a former Michigan QB, right?):

The only reason Drew Henson wasn't cut Wednesday was because the Cowboys wanted to check out his trade value. Considering his base salaries are guaranteed, don't expect any team to make a trade. That means he could be released as early as Thursday. It's pretty clear Henson never thrilled Bill Parcells -- and he controls who plays and who doesn't play in Dallas. Jerry Jones traded for Henson and thought he found his quarterback of the future. Parcells favored Tony Romo as his backup and wasted no time trying to convince Jones to sign Drew Bledsoe to try to take them to the playoffs. In the past couple years, for whatever reason, Henson got worse in Dallas instead of better.
