The news of Smith's eventual departure is not a huge shock, but it's very notable that the team would be amenable to possibly cutting Smith. Rapoport notes that the 49ers have a strong relationship with Smith and his agent, Tom Condon. They believe he's earned the right to pick a team and be treated right.
Rapoport reports that teams have noticed how Smith has handled this situation. Interested organizations don't view Smith as a long-term starter necessarily, but as a bridge quarterback. Teams know that if they draft a rookie, Smith will handle the situation well. Smith's experience running the spread in college could be attractive to a team like the Eagles.
In the end, Smith should not lack for options. He and Michael Vick will be the most attractive veteran options available (should Vick be released), and the weak quarterback draft class should make Smith even more attractive. It sounds like Smith might wind up getting to choose where he goes, rather than the 49ers choosing for him.
