The unlikely quarterback battle between No. 1 overall draft pick Alex Smith and career journeyman Shaun Hill will be determined early in the 2008 preseason.

49ers coach Mike Nolan says that each man will get extended playing time in the two preseason games, in the hopes of picking one to be the regular-season starter before the third exhibition contest.

It’s unclear whether one will have extended playing time in one of the two games and one will get the extended look in the other, or whether each will play a half of both games.  It’s also unclear whether Nolan will leave the starters on the field for more than the customary one or two drives in the first two exhibition games.

The news also means that performance during training camp practices will be a factor in the decision.  Apparently, the work of both players during the extensive offseason program has yet to yield a frontrunner.

Still, despite the ugliness that unfolded last year between Nolan and Smith, it’s hard not to think that the guy who was the No. 1 overall pick in the draft has the upper hand, and that Hill would have to significantly outplay Smith in order to get the job.
