Alex Smith’s Amazing Comeback(?)

[AnonEmouse]

How much does Smith cost us next season as a player compared to cutting him? Can't help wondering if on balance keeping him another season is really that expensive considering the vet leadership he brings. Kicking him to the kerb this offseason then bringing in another vet doesn't make sense to me if he can go one more year (or 2?). I know Rivera's said he wants to keep him anyway and I'd be surprised if he wants to retire now, so just hypothesising.
