QB Conundrum

Fooch already posted a Fan Post about the QB battle but I had some questions of my own and as I was writing my comment I realized it was a little too much for a just a comment. Hence:

 I think it's wrong to count out Huard from the initial QB comp, in a way. I think the chances of him starting are very slim, he's like the anti-JTO (how many of you just smiled real big when you read that?). Instead of being a boom or bust kinda guy, you know exactly what you're getting from him and that's above average drive control but not a whole lot else. Initially that sounds exactly like the kind of QB that Singletary wants but it won't be Huard for a couple of reasons. First, he's old, and though this may sound unfair, the saying goes with new coaches come new QBs. Singletary will be looking for "his" guy and a 36 yo QB won't be him. It could be different if that 36 yo QB was jurt Warner, but Huard doesn't have 2 MVPs. I like Huard a lot though, he's exactly what you'd want from one of the 3 QBs on your roster: an experienced vet who can help teach the young-uns and will perform very reliably on gameday, doing exactly what you ask of him; he can step in and not lose games and manage very well. The way I see it the other two QB slots should be filled with an up-and-comer, someone who has talent and potential who you can groom for later and an established starter. Obviously, this is an ideal situation. Sometimes the starter is the up-and-comer, sometimes you have two projects as backups. However, the Niners seem to be somewhere in the middle of all this. Shaun Hill is somewhere between established starter and reliable backup vet, we can't really know until he's played this season. Huard is the same but much more of the reliable backup vet mold. Alex Smith (and I know this will be debated) is somewhere between up-and-comer and...3rd QB. Again, we can't know until he can actually play another full season. The crux of this issue, for me, is that most of the Niners Nation (both the blog and the general fan base) seem to be clamoring for a QB to be taken somewhere in the draft. This would give the niners 4 QBs, begging the question, do the niners take an extra QB into the season? Or, if not, who's the odd man out? If we draft a QB and, presumably, he doesn't suck so much that we straight up cut him, do we risk having him ride it out on the practice squad? Does the reliable, but old, backup get shown the door. Does Alex Smith finally get labeled a bust, and get the boot out of SF, reduced contract and all? Does Shaun Hill magically fall out of favor and not make it to the regular season (unlikely, I know, but I'm running through all the options). Anyways, I find this quandry to be intruiging...
