Not sure why all the drama about Kap. Smith is the starter and will be for the forseeable future so it's not like Colin HAS to be ready right now. If something happens to Alex, Tolzien looks like a very capable backup and seems to have the same type of game as Smith does.
IMO, Smith and Tolzien are the tradtional west coast offense "present," while we make our Super Bowl run. Kap is the "future" (2-3 years down the road) while Harbaugh assembles the pieces to an unstoppable power/pistol/spread/read-option monster offense.
