If Hasselbeck survived the OL, he would have made a difference in the Browns game and possibly made the Bengals game more competitive (with a chance of winning that game). He may have helped them win the xmas eve game against the 9ers that TJack fumbled away late. Cardinals final game?
Definitely would have kept them from signing Flynn but they weren't resigning Whitehurst, so who would they have brought in before the draft? They probably would still draft Wilson, given the chance. If it was Matt vs Wilson in a 2-way competition and Wilson won, the local media and fans would have been more divided than they were with Flynn and Wilson. Softy, Hawkblogger, KJR and all the local beat guys would have whipped the fans into a frenzy.
Things worked out well for all involved. Moving on from Matt was always going to be a tough one but he got a chance to continue as a starter for awhile and now is backing up a pretty good young QB. It may have been harder for him to accept being the backup for the team he had been a starter of for 10 years.
